Plug socket for quick replacement of air switch with electricity

technical field

The invention relates to a low-voltage air switch, in particular to a plug socket for quickly replacing the air switch with electricity.

Background technique

Air switch, also known as air circuit breaker, is a very important electrical appliance in low-voltage power distribution network and electric drive system. It integrates control and multiple protection functions. In addition to completing contact and breaking circuits, it can also Short circuit, severe overload and undervoltage of circuit or electrical equipment are protected.

In the low-voltage distribution system, the air switch in the low-voltage distribution cabinet has been used for more than 10 years and is facing a large-scale replacement phenomenon. The traditional air switch replacement method is: cut off the knife switch in the power grid, and fix the conductive piece of the wire end in the power grid to the corresponding terminal of the air switch through screws. Since the air switch has six terminals, the process of replacing the air switch In the process, it is necessary to remove the six wire end conductive pieces one by one, and after replacing the new air switch, install the six wire end conductive pieces on the corresponding terminals of the air switch. This traditional air switch replacement method has complex replacement operation procedures and long replacement operations, which prolongs the waiting time for power outages and affects the normal power consumption of users.

There are anti-detachment hooks on the inner side; three conductive sheet mounting holes are arranged side by side at the upper and lower ends of the seat plate and run through the seat plate front and rear. The upper and lower conductive sheet mounting holes correspond one by one. Slide bars that go out of the seat plate are vertically arranged on each pressing piece, and adjusting nuts are installed on the end of the slide bar, and a compression spring is placed between the adjusting lock nut and the seat plate on the slide bar; The plug socket of the switch is also provided with a temporary conductive strip, and the two ends of the temporary conductive strip are bent, and the bending direction is consistent.

Further preferably, both ends of the pressing piece are wedge-shaped, which facilitates the insertion of the air switch and the conductive piece on the wire.

Further preferably, an insulating handle is provided on the temporary conductive strip to prevent electric shock.

The beneficial effects of the present invention are:

1. Since the pressing pieces are respectively set in the installation holes of each conductive sheet, the sliding rods passing through the seat plate are vertically arranged on each pressing piece, and the adjusting nut is installed on the passing end of the sliding rod, and the adjusting lock is located on the sliding rod. A compression spring is sleeved between the mother and the seat plate, and the plug seat of the charged quick-change air switch is also provided with a temporary conductive strip, and the two ends of the temporary conductive strip are bent, and the bending direction is consistent. When installing the air switch, insert the conductive piece of the wire end in the power grid into the corresponding conductive piece installation hole from front to back, and then insert the slide bar from the upper and lower ends of the seat plate into the corresponding conductive piece installation hole respectively, and pass through the corresponding conductive piece at the same time. Conductive sheet at the wire end, install the pressing sheet, compression spring and adjusting lock nut on the corresponding slide bar, and finally insert the conductive sheet at the terminal of the air switch into the corresponding mounting hole of the conductive sheet and clamp it between the conductive sheet at the wire end hold. When replacing the air switch operation, insert the bent ends of the three groups of temporary conductive strips from back to front into the corresponding upper and lower conductive sheet mounting holes, so that the temporary conductive strips are clamped between the pressing sheet and the conductive sheet at the wire end, and then Unplug the original air switch, insert the terminal conductive piece of the new air switch into the corresponding conductive piece installation hole between the pressure piece and the wire end conductive piece, and finally unplug the temporary conductive strip to complete the replacement operation. It simplifies the operation process of replacing the air switch, greatly shortens the replacement time, does not need to wait for power failure, and ensures the normal power consumption of users.

2. Since there is an air switch fixing frame symmetrically arranged on the front end of the seat plate, and an anti-detachment hook is provided on the inner side of the front end of the fixing frame, the air switch is installed between the two fixing frames, and the air is released by the anti-detachment hook inside the front end of the fixing frame. The front face of the switch is buckled, easy to disassemble, and the installation structure of the air switch is stable.
