A novel capacitor switch

Abstract

The invention discloses a novel capacitor switch. The capacitor switch includes a capacitor switch case, a first connecting block is fixedly connected with the top of the capacitor switch case, a second connecting block is fixedly connected with the bottom of the capacitor switch case, vacuum arc extinguishing devices are fixedly connected with the top of the first connecting block, connectors arefixedly connected with the top of the vacuum arc extinguishing devices, wiring porcelain bars are fixedly connected with the bottom of the second connecting block, and connection protection blocks are fixedly connected with the outside of the wiring porcelain bars. The closing of the switch is controlled by setting a magneto type operation device, the rapid switching of the capacitor is realized,when the switching is closing, inrush current is not bonded with moving contact connecting bars, the reignition cannot be generated during breaking, the voltage cannot appear, the damage probabilityof the capacitor is reduced, the advantage that the size of the inrush current is effectively controlled is reached, and the problem that the capacitor is damaged by the fact that the existing switchcannot effectively control the inrush current is effective solved.

Description

technical field [0001] The invention relates to the technical field of switching switches, in particular to a novel capacitor switching switch. Background technique [0002] The inrush current that will be generated when the capacitor is switched on, the size of the inrush current is related to the line impedance and the voltage difference between the capacitor and the power supply when the capacitor is switched on. When the inrush current is too large, it will cause damage to the capacitor. [0003] The capacitive switching switch is to reduce the size of the inrush current of the capacitor and ensure the service life of the capacitor. The existing switching switch has a simple structure and cannot effectively control the size of the inrush current, resulting in failure to protect the capacitor and causing damage to the capacitor. Contents of the invention [0004] The purpose of the present invention is to provide a new type of capacitor switching switch, which has the ...
