RESISTANCE DEVICE FOR HIGH-VOLTAGE CIRCUIT-BREAKER, AND HIGH-VOLTAGE CIRCUIT BREAKER

摘要

A resistance device for a high-voltage circuit breaker, and a high-voltage circuit breaker. The resistance device comprises at least two resistors (3, 6, 9, 12) surrounding a main conducting rod (14); each resistor is electrically connected in series to an adjacent resistor by means of an electrical connector (4, 7, 10) to form a resistor chain; each electrical connector is bridged and supported at the front or the rear of the two resistors that are electrically connected by the electrical connector; each electrical connector is provided with a support insulator (5, 8, 11) that is used to connect each connector with the main conducting rod; the front end portion of a first resistor in the resistor chain is provided with a resistor static contact (1) having the same orientation as a contact of the main conducting rod; and the last resistor in the resistor chain is provided with an electrical connection body (13) that is used to electrically connect said resistor to the main conducting rod. The present invention has a simple structure and is small. When the invention is used, all of the space around the main conducting rod can be fully utilized, thereby overcoming the problem in the prior art wherein resistance devices are large and difficult to install.
