Description

Technical Field

[0001] The utility model relates to the technical field of vacuum circuit breakers, in particular to an integrated vacuum circuit breaker which is easy to install and disassemble. Background Art

[0002] The "vacuum circuit breaker" is named because its arc extinguishing medium and the insulating medium of the contact gap after arc extinguishing are both high vacuum; it has the advantages of small size, light weight, suitable for frequent operation, and arc extinguishing without maintenance, and is widely used in distribution networks. The vacuum circuit breaker is an indoor distribution device in a 3-10kV, 50Hz three-phase AC system. It can be used for protection and control of electrical equipment in industrial and mining enterprises, power plants, and substations. It is particularly suitable for use in places that require oil-free, less maintenance, and frequent operation. The circuit breaker can be configured in a central cabinet, a double-layer cabinet, and a fixed cabinet to control and protect high-voltage electrical equipment.

[0003] The existing installation method for integrated vacuum circuit breakers is mostly to fix them on the mounting base through multiple bolts, so that the operator needs to turn the bolts multiple times during the installation or removal of the integrated vacuum circuit breaker, which makes the operation inconvenient and reduces the convenience of installation and removal of the integrated vacuum circuit breaker. For this reason, we propose an integrated vacuum circuit breaker that is easy to install and disassemble. Utility Model Content

[0012] The utility model adopts the above technical scheme, during installation, the base at the bottom of the circuit breaker body is installed in the installation groove, the base contacts and presses down with the pressure plate, and the pressure plate presses the pry plate to make the rotating plate rotate. When the base is completely installed in the installation groove, the fixing plate at the top of the rotating plate rotates to the top of the fixing seat, and the fixing seat is fixed in position. The fixing plate is fixed to the top of the fixing seat by inserting the plug rod into the plug hole, thereby completing the installation and fixing of the circuit breaker body. During disassembly, the locking rod is pulled upward so that the plug rod is pulled out of the plug hole to cancel the fixing of the fixing plate. At this time, the rotating plate is rotated to both sides and the circuit breaker body is lifted upward, and the fixing plate is rotated away from the top of the fixing seat, so that the circuit breaker body can be removed from the top of the mounting seat to complete the disassembly. When the circuit breaker body is installed and disassembled, the utility model does not need to be fixed with bolts, so that the bolts do not need to be rotated multiple times, thereby achieving the effect of facilitating the installation and disassembly of the integrated vacuum circuit breaker, and improving the convenience of installation and disassembly of the integrated vacuum circuit breaker.
