The invention discloses an easy-to-install low voltage breaker fixing device comprising a fixed plate; the top and bottom on the right side of the fixed plate are symmetrically provided with two fixedbolts; the left end of the fixed bolt penetrates the fixed plate and extends outside; the bottom on the right side of the fixed plate is fixedly connected with the first mounting plate; the top of the first mounting plate is fixedly connected with a slide rail; the surface of the slide rail is connected with a slide block in a slide manner. The first mounting plate, the slide rail, the slide block, the first connecting plate, a limit pin shaft, the second connecting plate, a movable plate, the second mounting plate, a limit vertical plate, a limit slot, a limit transverse slat, a pulling handle, a limit telescoping rod and a limit spring are arranged, so the low voltage breaker fixing device is easy to install, thus reducing work burdens of workers, preventing low voltage breaker damagescaused by installation accidents, preventing unnecessary economic losses, and bringing great conveniences for the workers.
Description
technical field [0001] The invention relates to the technical field of low-voltage electrical appliances, in particular to an easy-to-install low-voltage circuit breaker fixing device. Background technique [0002] A circuit breaker refers to a switching device that can close, carry and break current under normal circuit conditions and can close, carry and break current under abnormal circuit conditions within a specified time. Circuit breakers are divided into For high-voltage circuit breakers and low-voltage circuit breakers, the division of high and low voltage boundaries is relatively vague. Generally, those above 3,000 volts are called high-voltage electrical appliances. Circuit breakers can be used to distribute electric energy, start asynchronous motors infrequently, and protect power lines and motors. When they are seriously overloaded or short-circuited or under-voltage and other faults, they can automatically cut off the circuit. Its function is equivalent to the c...
