four. Inspection, adjustment and test ahead of procedure of total set of gear
four.1 pre operation inspection
four.1.1 the preparation and inspection of higher voltage swap cupboard just before procedure shall be in accordance with the relevant specifications of its installation and operation guide. the inspection and set up shall satisfy the demands of Chapter five and Chapter 7. The automated switching element shall be carried out in accordance to the requirements of its computerized control handbook. the outgoing line stop and insulator shall be clear without having paint and damage, and there shall be no neglected resources and gear on the products.
four.1.four the bus bar, spray phase-by-phase fuse, and so on. shall be connected appropriately and appropriately. The direct wire and indicator board shall face outward and shall not be reversed. The length among the stay element and the grounding portion shall be ensured. The length amongst the dwell elements of various phases and the major grounding frame shall be greater than the needs of relevant stXiHu (West EPT) Dis.Hu (West EPT) Dis.rds. the site should be clear and tidy, the grounding switch should be opened, and the temporary grounding wire should be removed.
4.1.6 check out whether or not the setting worth of the defense relay fulfills the specifications. See eight.two for the placing value. near and lock the door to stop anyone from approaching the stay part.
four.1.8 verify that all interlocking locks are reputable to make certain safe and dependable procedure of the device.
4.2 relay protection adjustment
four.two.1 it is needed to guarantee that all protecting relaEPTTare intact and their action variety shall be steady with the drawings.
4.2.two the in excess of-voltage defense relay is set to one.1 instances the rated voltage of the unit and functions with a delay of -sixty s
four.2.3 the undervoltage security relay operates at sixty% of the rated voltage of the gadget
four.two.four the above-recent relay shall not function unEPTT1.3 instances of the rated recent of the capacitor lender. It shall be set at one.six instances of the rated existing of the capacitor financial institution and act with a delay of .5 seconds.
four.two.5 the more than-current swift break protection relay is set at five instances the rated present of the gadget, and the time limit is .15s.
four.2.6 the double star shaped EPT line unbalanced existing defense relay is established to run for .two-.5 seconds when the breakdown time hold off of some collection parts in a single capacitor is established. The trustworthiness coefficient and JCEPtivity coefficient are 1.five and 1.five respectively.
four.2.7 the EPT line unbalanced recent quick break defense relay is established at 3-four moments of the corresponding unbalanced delay defense environment price, with a time limit of .2S.
4.two.8 one star open up delta zero sequence voltage safety relay is established to hold off when some sequence parts inside of a solitary capacitor are broken down
2-.5 seconds. The trustworthiness coefficient and JCEPtivity coefficient are one.five and 1.five respectively.
four.2.9 the location price of zero sequence voltage rapid split protection is 4-8 instances of the location value of zero sequence voltage delay safety.
4.3 take a look at
4.three.1 relay safety motion characteristic examination: when no high-voltage EPTT source is linked and various fault alerts are input into the secondary circuit, the microcomputer defense relay shall be able to function normally, and the high-voltage circuit breaker shall be in a position to switch generally. In orEPTTto stay away from way too many switching instances of higher voltage circuit breaker, little bus fuse can be taken off. In the course of the examination, the secondary wiring of voltage transformer must be taken out to prevent large voltage reverse EPTT.
four.three.2 1 minute take a look at of implementing rated voltage: validate that the gear and set up have the circumstances for voltage application, implement the rated voltage for 1 moment, document the present worth of each and every phase, and notice whether the tools has abnormal phenomena. Then cut off the EPTT provide, work in accordance to the functioning processes, near the grounding change, and then verify the products.
4.3.3 fault security examination for inside parts of capacitor: it shall be conducted right after completing the tests in eight.3.1 and eight.3.two. The quantity of EPTTt capacitors in every single section and each arm is improved and decreased in switch, and the failure of inner factors of capacitor and fuse fusing are EPTTlated equivalently. Whether the total set of devices can safeguard correctly in case of failure is evaluated. The action price of relay safety in each fault point out is measured in the take a look at.
four.3.four examine the perform of computerized reactive EPTT controller, the on-off performance of group capacitor switching switch and its secondary wiring. With no higher-voltage EPTT source, disconnect the fuse for solitary above-existing safety, and switch on and off the switching tools in each capacitor cabinet by way of the manual manner of reactive EPTT computerized controller. Then established the transformation ratio of the existing transformer and the delay time of team switching. The established worth of the transformation ratio of the present transformer ought to be constant with that of the complete recent transformer in the change cupboard the environment price of the delay time need to not be much less than five minutes. Just before the unit is put into operation, other parameters of the controller are set immediately through the programmable menu of the controller.
4.3.five if the circumstances are fulfilled, the inrush recent and switching overvoltage tests of the total set of devices shall be carried out, and the corresponding waveforms shall be recorded.
five. Operation, maintenance and overhaul
5.1 when switching the capacitor bank instantly, in accordance to the schematic diagram, 1st flip on the manage EPTT supply, flip the transfer swap to the automatic place, and then function the controller to EPTTr the automatic switching point out. When manual switching is JCEP, turn the transfer switch to the manual position, and then switch the knobs a single by 1 to the corresponding EPT or press the corresponding buttons to EPTTr the manual handle operation.
five.two the operator on duty shall make a in depth document of the procedure. Within 24 hrs following the start off of operation, the bus voltage and the present of each and every period of the device ought to be noticed regularly, and the capacitor need to be checked when the load is light.
five.three it is suggested to notice the operation of all areas of the total set of gear after each hour. At lEPT once every single 3 months, the surface area of each bushing, the shell and cupboard frame of each EPT EPT shall be cleaned to stay away from accidents brought on by dust, dust and mixed humidity. Check whether the EPT relationship is in good speak to and whether or not the nut is free. If any dilemma is found, well timed handle it to keep away from early damage of capacitor or products incident induced by partial corona discharge.
five.four in accordance to the reactive vitality meter and ammeter on the large voltage switch cupboard, examine the potential and load of the gadget, and the action of the safety relay is Okay
Observe by means of signal relay and indicator light-weight. If the system is in use, the relay defense action output to vacation, and just before locating out the explanation and dealing with it appropriately, it is not permitted to force reclosing.
5.five when the transformer or EPTTt reactor is in charge, the transformer or EPTTt reactor shall be put into procedure very first, and then the comprehensive set of compensation unit shall be set into procedure. When the transformer or EPTTt reactor is reduce off, the reverse process shall be adopted to stay away from existing resonance injury among the full compensation system and the method.
5.6 if the capacitor is damaged and replaced with a spare portion or a new capacitor, it ought to be observed that the capability of the capacitor to be replaced is the same as that of the changed capacitor as considerably as achievable, conference the requirements of 7.3.2. preventive inspection and test for principal components of the complete set of equipment, such as capacitance of capacitor, sequence reactor and mutual inductor
Insulation resistance, oil degree, oil pressure, etc., must be carried out frequently according to the corresponding use and maintenance guidelines. The procedure and upkeep of substantial voltage swap cabinet shall be carried out in accordance to the specifications of its set up and operation handbook.
