Abstract

An arc extinguish chamber (1) for an isolated circuit breaker and an isolated circuit breaker using the arc extinguish chamber. The isolated circuit breaker includes an arc extinguish chamber, wherein the arc extinguish chamber is provided with a fixed main contact (7), a moving main contact (10), a fixed arcing contact (5) and a moving arcing contact (11) arranged in an up-to-down direction, the fixed main contact and the fixed arcing contact are located above the moving main contact and the moving arcing contact corresponding thereto when the isolated circuit breaker is open, the fixed arcing contact and the moving arcing contact are located on inner sides of the fixed main contact and the moving main contact, a shield cover (8) shielding the fixed arcing contact when the circuit breaker is open is disposed between the fixed arcing contact and the fixed main contact, and the shield cover has a lower shield end located below the fixed arcing contact when the circuit breaker is open. By arranging a shield cover in the arc extinguish chamber, the isolated circuit breaker can be used as a circuit breaker and an isolating switch, which has a simple structure, is easy to use, and can effectively reduce design and manufacturing costs of the isolated circuit breaker.

Description

technical field [0001] The invention relates to an arc extinguishing chamber for an isolating circuit breaker and an isolating circuit breaker using the arc extinguishing chamber. Background technique [0002] With the continuous improvement of circuit breaker technology and reliability, in order to reduce costs, reduce the use of power equipment, and reduce the area occupied by power stations, when designing power equipment, the isolation function is mostly integrated into the circuit breaker. An isolating circuit breaker that can be used as an isolating switch with an isolating function. [0003] For example, a high-voltage isolation circuit breaker is disclosed in the publication specification of the Chinese invention patent application with the publication number CN101589446A. The moving main contact and moving arc contact inside the arc extinguishing chamber move to realize the operating mechanism of the circuit breaker opening and closing operation. Complete the clos...
