Description

Technical Field

[0001] The utility model relates to the field of load switches, and specifically to a vacuum arc extinguishing type load switch. Background Art

[0002] The working principle of a vacuum arc extinguishing type load switch is mainly based on vacuum arc extinguishing technology. Inside the switch, there is a pair of contacts placed in a vacuum environment. When the load switch needs to connect the circuit, the operating mechanism moves the moving contact towards the static contact. When the contacts touch, the current can pass through. And when it is necessary to disconnect the circuit, the operating mechanism drives the contacts to separate. Since the contacts are in a vacuum environment and there are almost no gas molecules in the vacuum, the arc generated at the moment of contact separation can be quickly extinguished. This is because the insulation strength of the vacuum is very high, which can effectively limit the development and maintenance of the arc, thus achieving quick and reliable current interruption.

[0003] When installing a vacuum arc extinguishing type load switch, the switch body is firmly installed on the switch cabinet or bracket by bolts or other fixing methods. Ensure the installation is stable and vertical to ensure the normal operation and operation of the switch.

[0004] When the load switch is actually installed, it cannot be applied to an uneven installation surface. After installation, the load switch is prone to being in an inclined state, affecting its normal operation. Content of the Utility Model

At the same time, the first mounting frame includes a positioning piece, and a positioning opening is formed on the positioning piece. Two groups of fixing studs are inserted into the positioning opening, and the bottoms of the two groups of fixing studs are welded and fixed on the load switch body. At the same time, fixing nuts are screwed and installed on the two groups of fixing studs. A support seat is welded and fixed on the upper side of the end of the positioning piece, and an adjusting plate is inserted into the support seat. At the same time, a fixing seat is welded and fixed on the top of the adjusting plate, and a locking plate is welded and fixed on the top of the fixing seat.
