A capacitor discharge device

Abstract

The invention discloses a capacitor discharge device and relates to the technical field of capacitors. It consists of insulating rods, discharge conductors and grounding conductors. The discharge conductor includes a fixed frame and two elastic arms connected with the fixed frame, the fixed frame is connected with one end of the insulating rod, and the two elastic arms are arranged at intervals relative to each other. The two elastic arms are configured to simultaneously cover the positive and negative contacts of the capacitor to be discharged when they are opened, and respectively press against the outside of the positive and negative contacts when they are closed; or are configured to protrude into the Between the positive pole contact and the negative pole contact, and press against the inner sides of the positive pole contact and the negative pole contact respectively when opened. The contact side of the elastic arm and the contact of the capacitor is also respectively provided with a first socket capable of engaging with the positive electrode contact and a second bayonet socket capable of engaging with the negative electrode contact. When discharging through the capacitor discharge device, the physical strength of the operating personnel can be greatly saved, good contact with the capacitor contacts can be ensured, and residual charges can be exhausted.

Description

technical field [0001] The invention relates to the technical field of capacitors, in particular to a capacitor discharge device. Background technique [0002] When the parallel capacitor bank disconnects the circuit breaker and disconnects from the grid, because the moment of disconnection is at a high voltage moment, there is still a lot of charge on the capacitor bank, and the voltage at both ends of the capacitor bank is very high. For this reason, discharge coils are installed at both ends of the capacitor bank. After the capacitor bank is disconnected from the power supply, the residual voltage on the capacitor bank can be reduced to 50V or below within 5 seconds. Even so, however, residual charge remains in the capacitor bank. Therefore, in order to prevent the residual charge from threatening personal safety, the power industry stipulates that each capacitor in the capacitor bank should be discharged several times one by one before working on the capacitor bank or e...

Problems solved by technology

[0004] However, when using these discharge tools, since the discharge conductor is pressed against the contact of the capacitor by manpower, it will cause the operator to consume more physical strength, and the discharge conductor often slides on the capacitor contact, etc., resulting in discharge Poor contact between the conductor and the capacitor contact, it is difficult to discharge the residual charge in the capacitor, which may cause electric shock accidents
