High voltage signal-generator discharge apparatus

Abstract

The invention relates to a high voltage signal-generator discharge apparatus which includes a swing rod charging and discharging mechanism and a driving mechanism which drives the swing rod charging and discharging mechanism to swing. The swing rod charging and discharging mechanism includes an anode swing rod, a cathode swing rod, a charging connecting plate and an insulating baffle plate. The anode swing rod and the cathode swing rod are provided with a connection shaft therebetween. The two ends of the connection shaft are in respective rotation connection to the anode swing rod and the cathode swing rod. The anode swing rod and the cathode swing rod are provided with a discharging contact and a charging contact thereon. The discharging contact and the charging contact are connected therebetween to a capacitor connecting line which is connected to a capacitor. The discharging contact is connected to a fault cable. The charging contact is connected to the charging connecting plate. Compared with prior art, the apparatus realizes complete separation between charging operations and discharging operations in charging and discharging, allows separate operation of the charging and discharging, has no cross influence, and guarantees operation stability of the entire apparatus.

Description

technical field [0001] The invention relates to a discharge device, in particular to a discharge device for a high-voltage signal generator. Background technique [0002] With the development of society, the application of power cables is becoming more and more extensive. Using cables for power supply has many advantages. However, due to the impact of factors such as system expansion, the longer the running time, the more frequent cable failures. In order to improve the reliability of power supply, it is necessary to These cable faults must be repaired in short order. [0003] The cable test high-voltage signal generator is mainly used for the test of high resistance and flashover faults of power cables. It can generate high-voltage DC high voltage to make the cable fault click through and discharge, and cooperate with the cable fault distance measurement and fixed point instrument for distance measurement and fixed point. There are three main working modes of the high volt...

Problems solved by technology

However, these discharge methods have many technical defects in the specific use process: ① When the high-voltage source is charging the capacitor, its grounding wire is in a connected state, and the two processes of charging and discharging cannot be completely separated; At the moment when the faulty cable discharges, the high voltage will be fed back to the high voltage source, causing damage to the high voltage source, especially to the control part of the high voltage signal generator.
