Abstract

The invention relates to a resistance sheet crimping structure and a circuit breaker in the field of a high-voltage switch. The resistance sheet crimping structure comprises an insulation support, wherein the insulation support is used for installing resistance sheets which are arranged in a lamination way, an elastic piece and a pressure applying piece are arranged on the insulation support, the elastic piece is used for providing an elastic press force for the resistance sheets, the pressure applying piece is used for propping against the elastic piece and is movably arranged on the insulation support by a threaded transmission mechanism or is connected with a push piece in a transmission way so as to be movably arranged on the insulation support, and the push piece is connected onto the insulation support in a threaded transmission way. During application, the compression quantity of the elastic piece is changed by rotating the pressure applying piece or the push piece, so that the press force of the resistance sheets is further adjusted. Compared with an existing resistance sheet, other components are not needed to be disassembled during the adjustment process of the resistance sheet crimping structure on the resistance sheets, the resistance sheet crimping structure is convenient to operate and is relatively high in adjustment efficiency.

Description

Technical field [0001] The invention relates to a resistance piece crimping structure and a circuit breaker in the field of high voltage switches. Background technique [0002] In the high-voltage power grid system, when the circuit breaker is closed, overvoltage will be generated, which is harmful to the power grid system; generally, the circuit breaker is required to be combined with the switching resistance in the power grid system above 330kV, and the closing resistance is more than the arc extinguishing chamber The main contact is turned on 8-11ms ahead of time, and part of the electrical energy in the power grid is absorbed and converted into heat energy by the closing resistance, so as to reduce electromagnetic oscillation and limit overvoltage; most of the existing closing resistance is caused by excessive A single ceramic resistor chip is stacked and arranged to be crimped. According to the actual circuit parameters, different specifications and quantities of resistor ch...
