Light controlled vacuum switch module

Abstract

The invention provides an optically controlled vacuum switch module and relates to a power high-voltage switch. The optically controlled vacuum switch module is characterized in that based on the prior vacuum switch and the prior photoelectric technology, the optically controlled vacuum switch module is constituted; an operating mechanism is directly connected with interrupter equipotential; a battery and a capacitor controlled by an optoelectronic device are used to supply power to the mechanism; and an induction power coil gets electricity from a system to supplement the battery and the capacitor, controls movements of the mechanism at a cool end through optical fiber, and operates a vacuum interrupter to complete current connection and current breaking. A certain amount of optically controlled vacuum switch modules can be connected in series according to voltage grades to constitute a high-voltage level vacuum switch, so as to replace the prior SF6 gas high voltage switch with an greenhouse effect; and the optically controlled vacuum switch module has the advantages of simple structure and convenient realization in industry, and fiber control signals can be directly controlled by a computer of the power system.

technical field [0001] The invention belongs to the field of electric high-voltage switches, and relates to a practical light-controlled vacuum switch module technology, which is used to form a modular high-voltage vacuum switch. Background technique [0002] At present, there are two new types of high-parameter switches in the field of high-voltage switches, vacuum switches and SF6 switches. SF6 switch has good insulation performance, but its leaked exhaust gas is harmful to human body and has greenhouse effect. The vacuum switch has the best performance, but in the application of high voltage level greater than 35kV, the insulation of long vacuum gap has insurmountable difficulties. The application of multiple fractures in series has problems in the operating mechanism: the existing high-voltage switch operating mechanism is located at the ground potential, and the insulation structure between the interrupter and the arc extinguishing chamber is complicated, especially fo...

Problems solved by technology

The performance of vacuum switch is the best, but in the application of high voltage level greater than 35kV, the insulation of long vacuum gap has insurmountable difficulties

The application of multiple fractures in series has problems in the operating mechanism: the existing high-voltage switch operating mechanism is located at the ground potential, and the insulation structure between the interrupter and the arc extinguishing chamber is complicated, especially for ultra-high voltage and multiple fractures. The structure is more complicated and the cost is also higher. high

In addition, the existing high-voltage switch operating mechanism is also difficult to be directly controlled by the computer system
