Abstract

The invention discloses a 220V low-voltage electric vacuum load switch and belongs to the technical field of electric power. The 220V low-voltage electric vacuum load switch can realize automatic control in a power distribution network control system and meet the demand for intelligent control of a power distribution network. A micro-electric push-puller is adopted as a power source of the switchand controlled by a 12V direct-current power supply, and the switch is not affected by whether a control circuit is powered or not. The problem about arc extinction of the low-voltage large-load switch is solved by adopting a vacuum arc extinguishing chamber, and vacuum degree is guaranteed by mounting a micro-vacuum pump; the switch operates stably and accurately during switching on and off; a display identification role in switching on and off is played by a manual button, and the switch is convenient to use during maintenance or detection.

Description

technical field [0001] The invention relates to the technical field of electric power, in particular to a 220V low-voltage electric vacuum load switch. Background technique [0002] With the demand for intelligence in the distribution network, large-load electric switches are gradually used to remotely control or remotely automatically control the automatic control system of the distribution network. Strong arc; not only that, the existing low-voltage switch and the control circuit use the same power supply, and the use of the switch is affected by whether the control circuit has electricity. Contents of the invention [0003] In order to solve the above problems, the invention discloses a 220V low-voltage electric vacuum load switch. [0004] The present invention is achieved through the following technical solutions: [0005] A 220V low-voltage electric vacuum load switch, including an insulating box, three fixed contacts are fixed on the top of the insulating box, an ...
