Low-voltage multipurpose short-circuit connector

Abstract

The invention discloses a low-voltage multipurpose short-circuit connector, comprising fixing clamps, flexible jumping wires and a short-circuit connecting member, wherein each fixing clamp comprises a conductive fixing member and a conductive adapting member; each of the flexible jumping wires is a conductive braided strap; each of two ends of each conductive braided strap is provided with a connecting hole; the short-circuit connecting member comprises a back plate which is made of a material with an insulating arc-isolating effect and is used for fixation; the back plate is provided with installation holes which are adapted to fuse wires with different pitches and the size of a base; the fuse wires are arranged on the base. In the field application, the low-voltage multipurpose short-circuit connector disclosed by the invention can be used as an effective measure for quickly repairing and recovering electric power after switches with different models and different specifications are in fault, and can also be fixedly used as the leading end of a short-circuit connection grounding wire. According to the low-voltage multipurpose short-circuit connector, not only are the problems that the rush repairing time is long due to the fact that a switch is not matched, and the power fault range is large solved, but also the problem that the leading end of the overhauling grounding wire of most switches cannot be installed is solved, and the operation efficiency and power supply reliability are improved.

Description

technical field [0001] The invention relates to a short connector, in particular to a low-voltage multipurpose short connector. Background technique [0002] A low-voltage circuit breaker is a switching device that can not only switch on and off normal load current and overload current, but also switch on and off short-circuit current. In addition to the control function in the circuit, the low-voltage circuit breaker also has certain protection functions, such as overload, short circuit, undervoltage and leakage protection. At present, low-voltage circuit breakers are widely used in my country's low-voltage distribution network from the power distribution substation to the customer-side electric meter. [0003] The application of low-voltage circuit breakers mainly has the following characteristics. First, low-voltage switches are used in the largest number of molded case circuit breakers, with thousands of types. However, there are obvious differences in the structure a...

AI Technical Summary

Problems solved by technology

[0004] The above switch application features play a positive role in saving the manufacturing size of the switch cabinet and reducing the floor space, etc., but it also brings a series of problems in the operation and maintenance of the switch, mainly because once the switch is damaged and other faults will occur: The maintenance grounding wire of a single circuit in the narrow cabinet space cannot be installed, and the power failure circuit and area need to be expanded; second, when replacing switches with various types and sizes, there is often no spare switch of the same model to replace, and other switches cannot be replaced. It often takes a lot of time to find a switch that can be used. Once you can't find it, you can only change the continuous mode of the busbar, which will cause a double delay in the power failure time.
