Abstract

A double-break disconnector switch module comprises a shell, double-break switch devices and driving mechanisms. The shell is internally provided with n closed cavities which are communicated in sequence, and each cavity is internally provided with a set of double-break switch devices and a set of driving mechanisms. Each double-break switch device includes a moving contact base, a pair of moving contacts and a pair of static contacts. Each moving contact base is arranged in the middle of the corresponding cavity. The static contacts in each pair are arranged at the two opposite sides of the corresponding moving contact base. The moving contacts in each pair are arranged inside the corresponding moving contact base and can extend out of the moving contact base from opposite directions to be in contact with the corresponding static contacts for cooperation. The moving contacts in each pair are driven by the corresponding driving mechanism to do reciprocating linear motion synchronously to be in contact with or separated from the corresponding static contacts at the same time. The moving contacts in each pair are in conducting connection with each other. The double-break switch devices in each cavity are synchronously separated or connected by the driving mechanisms. The advantage is that the double-break switch devices adopt a three-phase linkage mechanical transmission structure, and transmission is stable and reliable.

Description

technical field [0001] The invention relates to the equipment field of converter stations / substations with a voltage level of 220kV and above, and more specifically relates to a double-break isolating switch module. Background technique [0002] Isolating switch (commonly known as "knife switch") generally refers to a high-voltage isolating switch, that is, an isolating switch with a rated voltage above 1kV, usually referred to as an isolating switch. The 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. The main feature of the isolating switch is that it has no arc extinguishing ability, and can only open and close the circuit under the condition of no load current. The isolating switch is used at all levels of voltage to change the circuit connection or to isolate the line or equipment from the power su...
