Abstract

The invention discloses an isolating switch, and relates to the field of low-voltage apparatus component equipment. A rapid switch-on and switch-off mechanism and an switch-on and switch-off padlock mechanism are arranged on a body of the isolating switch, the rapid switch-on and switch-off mechanism is used for cutting off the isolating switch during power failure, and the switch-on and switch-off padlock mechanism is used for realizing a switch-on and switch-off padlock function without depending on a handle. When power is required to be cut off, the isolating switch is cut off only through the rapid switching-on and switching-off mechanism, so that the safety performance of the switch is improved. Meanwhile, the isolating switch is provided with the switch-on and switch-off padlock function on the body, switch-on and switch-off padlock can be realized without relying on the handle, and misoperation is prevented.

Description

technical field [0001] The invention relates to the field of low-voltage electrical components and equipment, in particular to an isolating switch. Background technique [0002] In order to provide circuit breaker protection and overcurrent protection for power transmission and distribution circuits, it is usually necessary to connect fuses in series in the power distribution circuit as protective devices, and at the same time, it is necessary to install an isolating switch and control the circuit through frequent manual operations. The isolating switch realizes the opening and closing of the moving and static contacts through the included operating mechanism, but the existing operating mechanism has a complicated design, many parts, and high cost, and the padlock function of the isolating switch is on the handle, and only the opening padlock cannot prevent misuse. operate. Contents of the invention [0003] The object of the present invention is to provide an isolating s...
