[0003] The traditional outdoor pole-mounted vacuum circuit breaker is provided with mounting plates on both sides of its base. The conventional installation method first fixes the mounting bracket on the utility pole, then places the vacuum circuit breaker on the mounting bracket, and then installs the bolts one by one by the operator. One is connected between the installation plate and the installation bracket to achieve the function of fixed installation; the installation of the outdoor vacuum circuit breaker on the pole is basically at high altitude, this installation method is too cumbersome, it is not easy for the operator to operate, and at the same time it improves the operator's safety.

The invention discloses an outdoor pole-mounted vacuum circuit breaker, and relates to the technical field of vacuum circuit breakers. The vacuum circuit breaker comprises a vacuum circuit breaker body, a mounting assembly and a supporting assembly. The mounting assembly comprises mounting rods which are horizontally, symmetrically and fixedly arranged on a carrier; an opening is formed in the side surface of each mounting rod; the openings of the two mounting rods are arranged oppositely; mounting plates are fixedly arranged at the two sides of the bottom end of the vacuum circuit breaker body; the two mounting plates are respectively mounted in the openings of the two mounting rods in a sliding manner; mounting cavities are respectively formed in one side walls of the openings of the twomounting rods; elastic pieces are installed in the installation cavities and connected with lock rods, lock holes matched with the lock rods are formed in the two installation plates respectively, the elastic pieces drive the lock rods to be inserted into the lock holes, locking assemblies used for closing the openings are installed at the ends, away from the ends connected with the carrier, of the installation rods, and the supporting assemblies are connected with the installation rods. The vacuum circuit breaker is convenient to install and operate, improves the installation efficiency, andreduces the labor intensity of an operator.
Description
technical field [0001] The present invention relates to the technical field of vacuum circuit breakers, more specifically, it relates to an outdoor post-mounted vacuum circuit breaker. Background technique [0002] Vacuum circuit breaker is named for 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 no maintenance for arc extinguishing. The application is more popular; the outdoor column-mounted vacuum circuit breaker is suitable for a three-phase AC 50Hz power system with a rated voltage of 12kV, which can break and close the line load current, overload current and short-circuit current. It is widely used in line segmentation, protection and control of substations, urban and rural power grids, and power distribution systems of industrial and mining enterprises, and is more suitable for rural power grids and places with...
