Enclosed outdoor isolating switch

Abstract

The invention discloses a closed outdoor isolation switch, which relates to the technical field of power switches and comprises a protection box, a base is fixedly arranged on the protection box, a cable is arranged in the protection box in a penetrating manner, a connection part is movably arranged in the protection box and used for clamping and connecting the cable, and the connection part comprises two groups of clamping arms. A communication clamping arm is movably arranged on the clamping arm, and the clamping arm moves to the cable and clamps the cable through the communication clamping arm, so that a circuit is connected; a control part used for controlling the connection part to be connected with the cable is fixedly arranged on the base, a ratchet wheel assembly is arranged on the control box and used for driving the driving shaft in a one-way mode, the purpose of controlling connection and disconnection of a circuit is achieved through elastic potential energy of a spring, the protection problem of the circuit outdoors is solved, and safety accidents are avoided.

Description

technical field [0001] The invention relates to the technical field of power switches, in particular to a closed outdoor isolating switch. Background technique [0002] Isolating switch, generally refers to a high-voltage isolating switch, that is, an isolating switch with a rated voltage of 1kV and above, usually referred to as an isolating switch, which is the most widely used electrical appliance in high-voltage switching appliances. Its working principle and structure are relatively simple , but due to the large amount of use and high reliability requirements, it has a greater impact on the design, establishment and safe operation of substations and power plants. [0003] There are some problems in the current isolating switch, especially for the outdoor isolating switch. Due to the rest of the line connection, it is easily disturbed by external factors and does not have corresponding functions, such as antifreeze, rainproof and dustproof functions, especially in rainy w...

[0002] Isolating switch, generally refers to a high-voltage isolating switch, that is, an isolating switch with a rated voltage of 1kV and above, usually referred to as an isolating switch, which is the most widely used electrical appliance in high-voltage switching appliances. Its working principle and structure are relatively simple , but due to the large amount of use and high reliability requirements, it has a greater impact on the design, establishment and safe operation of substations and power plants

[0003] There are some problems in the current isolating switch, especially for the outdoor isolating switch. Due to the rest of the line connection, it is easily disturbed by external factors and does not have corresponding functions, such as antifreeze, rainproof and dustproof functions, especially in rainy weather. It is easy to cause safety hazards. The current isolating switch is generally operated manually to control the on-off of the circuit. The control handle is generally connected with a circuit, which is likely to cause a safety accident. Therefore, a device that can be controlled indirectly and has an outdoor Isolating switch for self-protection function

[0004] The Chinese invention patent with publication number CN113539732A discloses a push-pull outdoor isolating switch, which can effectively improve the current-carrying capacity and action accuracy of the isolating switch, and at the same time improve the heating problem caused by poor contact; problem, the patent does not propose an effective technical solution
