The invention relates to the technical field of power distribution devices, and discloses an automatic protection power distribution switch device capable of avoiding short circuit. The equipment comprises a device shell, a power connection plate is arranged in the middle of the interior of the device shell, a limiting plate is arranged on the side surface of the interior of the device shell, a shearing mechanism is welded on the side surface of the limiting plate, an ejector rod is in sliding connection into the limiting plate, a limiting spring sleeves the ejector rod, and a belt is hinged to the front side of the ejector rod. According to the automatic protection power distribution switchgear capable of avoiding the short circuit, through cooperative use of the shearing mechanism and the belt, when the working temperature in the device shell is too high and the operation of the switchgear is influenced, the shearing mechanism can cut off the shearing mechanism, the ejector rod is limited by the limiting spring to enable the conductive block to be separated from the power connection plate, and therefore the automatic power-off effect is achieved; and through cooperative use of the ejector rod and the conductive top plate, when the equipment is powered off, the ejector rod is in contact with the conductive top plate, so that an alarm is triggered to prompt people to carry out maintenance.
Description
technical field [0001] The invention relates to the technical field of power distribution devices, in particular to an automatic protection power distribution switchgear for avoiding short circuit. Background technique [0002] The function of the power distribution device is to receive and distribute electric energy during normal operation, and to quickly remove the faulty part and restore normal operation through automatic or manual operation when a fault occurs. It can be said that the power distribution device is an important device to realize the function of electrical main wiring. In switchboards for high voltage reception and distribution systems, mobile mechanisms provided with circuit breakers are formed as a unit. The switchboard may break out in fire during use. The reasons for the fire are: poor contact between the connecting wire and the electrical instrument, resulting in an increase in its own contact resistance, which will cause its own heat to rise for a lo...
