Example Embodiment

[0010] Example: such as figure 1 As shown, the lightning arrester counter remote clearing device is composed of a current generator 2 installed on the upper part of the insulating rod 1 and a power supply 5 connected to the current generator 2. The current generator 2 includes a power switch, a signal generator, an output amplifier, and a current output terminal. The signal generator is connected to a power source 5 and a remote control circuit board through a wire 4, and the current output terminal is the electrode 3. The signal generator can use existing technology, for example: it is composed of an LC oscillator and a buffer, the inductance in the oscillating circuit of the LC oscillator is composed of a magnetic core, a primary coil and a secondary coil, the primary coil and The capacitor forms an LC oscillating circuit. One end of the secondary coil is grounded, and the other end is connected to the fixed contact of the changeover switch. The movable contact of the changeo...

Abstract

The invention relates to a remote control zero clearing device of arrester counters. The remote control zero clearing device is composed of a current generator installed on the upper portion of an insulation rod and a power source which is connected with the current generator. The current generator comprises a power switch, a signal generator, an output amplifier and a current output end. The signal generator is connected with a remote control circuit board through a wire and the power source and the current output end is an electrode. The remote control zero clearing device is simple in structure, enables low level to be output through remote control, can conduct zero clearing on the arrestor counters of 110kV, 220kV and 750kV transformer substations quickly and frequently without the need of power cut and can guarantee that the cumulative times of actions on the arrestor counters is the same as the cumulative times of actions of a monitor. During operation, electricity leakage is avoided through the insulating rod and the safety of operators is guaranteed.

Description

technical field [0001] The invention relates to a remote-control clearing device for a lightning arrester counter. Background technique [0002] The lightning arrester counter is a high-voltage electrical appliance used by the substation to monitor and count the number of lightning strikes of the lightning arrester online. It uses 0-99 cycle counting and adds 1 to the lightning strike counter each time. At the same time, it sends a pulse signal to the monitoring and control server through the communication port, and the monitoring machine After the measurement and control server receives the pulse signal, it shows that the number of arrester actions has accumulated once. Before the substation is put into operation, if the communication of the monitoring machine is interrupted during the arrester test, the monitoring machine will not receive the action pulse signal of the arrester, resulting in the accumulation of actions on the arrester counter. The number of times is incons...
