Device for manufacturing knife switch static contact and manufacturing method of knife switch static contact

Abstract

The invention relates to the technical field of electric power and tools, and particularly relates to a device for manufacturing a knife switch static contact. The device is characterized by comprising two opposite brackets, a base (43), two support plates (44), four fifth fixing elements (45) and two support connecting plates (46). The invention also discloses a manufacturing method of the knifeswitch static contact. The device mainly has the following beneficial technical effects: the structure is simple, the component parts are easy to manufacture and easy to replace, the assembly time isshort, the maintenance is easy, the power outage time of the busbar is short and the output power quantity is higher; and the manufacturing method is simple and easy to master.

Description

technical field [0001] The invention relates to the technical field of electric power and tools, in particular to a device for making a static contact of a knife switch and a method for making the static contact of a knife switch. Background technique [0002] Tubular busbar is a busbar structure commonly used in substations. Its main function is to collect and distribute electric energy. Compared with another commonly used busbar, soft busbar, it has the advantages of large carrying capacity and good heat dissipation conditions. It is mostly used in 220kV And above the voltage level; the static contact is fixed on the tube mother, when the isolating switch is closed, the moving contact below it rises to clamp the static contact on the upper busbar, so as to achieve conduction. At present, in the substations with a voltage level of 220kV and above in the State Grid Corporation of China, the busbars with a voltage level of 110kV and above mostly use tubular busbars. Clamp an...

Problems solved by technology

At present, in the substations with a voltage level of 220kV and above in the State Grid Corporation of China, the busbars with a voltage level of 110kV and above mostly use tubular busbars. Clamp and fix the static contact on the tubular bus to realize the closing of the isolating switch. When the isolating switch on the bus side is installed on site, the moving contact is generally a finished product from the manufacturer and can be assembled on site, while the static contact generally has no finished product. , needs to be produced on site; and due to the rapid development of the power industry, the demand for static contacts of tubular busbars generated by newly added 220kV substations every year and new intervals in 220kV substations is increasing, and the production of static contacts must After the bus is powered off, the measurement can be carried out first, so the time for making static contacts will take up precious bus power outage time; and the production of tubular bus static contacts on site generally requires four people, and a set of isolating switches has a total of three static contacts. It takes about 5 hours to make the head, not including the measurement time, which consumes a lot of manpower and time costs, increases the power outage time of the bus, and results in a decrease in output power and power consumption income.
