Dingfeng Capacitor----How to Install Capacitor

Jun 6,2016

1 When installing a capacitor, the connection of each capacitor had better use separate cord connected to the bus, do not use hard bus connection, in order to prevent the assembly stress capacitor casing damage, caused by the sealing of the spill.

2 Any bad contact of capacitor circuit, may cause high frequency oscillations arc, the work intensity of electric field in the capacitor increase and fever and early damage.Therefore, when installation must keep contact and grounding part of the electric circuits of the good.

3 Low voltage grade after series of capacitor network running on high voltage grade, between the Taiwan the shell of the earth, should by adding the equivalent of running voltage grade insulator, reliable insulation.

4 Capacitor after star connection, rated voltage for high level, and the neutral point grounding, capacitor insulation shell to deal with.Before the installation of capacitor, to assign a capacitance, and white balance, deviation is less than 5% of the total capacity.When installed with relay protection device should also meet the balance current error is not more than the requirements of relay protection action current.

6 For individual compensation capacitor's wiring should be: to start or directly by the rheostat starting of induction motor and its improving power factor of the capacitor can be directly connected to the outlet terminals of the motor, don't switch installed or fuse between;On the star - delta starter start induction motor, had better use three single-phase capacitor, each capacitor in parallel at each phase winding directly on the two terminals of the connection of the capacitor is always consistent and winding method.

7 Low voltage capacitor compensation for the group, the connection should be on the outer edge of the low pressure group bus power switch, in order to prevent the grouping bus bar, the switch is off since the excitation of the phenomenon.

8 Concentrated compensation of low voltage capacitor Banks, we should set up the switch is installed on the outer edge of the line switch, rather than in a low voltage on the bus.
