Remote control prepayment type self-recovery low-voltage power distribution box

Abstract

The invention discloses a remote control prepayment type self-recovery low-voltage power distribution box, which comprises a main box body and an auxiliary box body, wherein the main box body is arranged to be a rectangular box body, a box door is arranged on the main box body, a first ventilation hole is formed in the rear wall of the main box body, the auxiliary box body is fixedly connected to the outer side of the rear wall of the main box body, one side wall of the auxiliary box body is open, an inner box body is slidably connected into the auxiliary box body, the side wall, close to the main box body, of the inner box body is open, and a fixing mechanism is arranged on the rear wall of the auxiliary box body. According to the scheme, the auxiliary box body is arranged behind the main box body, and the auxiliary box body can be used for bearing part of electronic elements, so that the electronic elements in the main box body are prevented from being arranged too densely.

Description

technical field [0001] The present application relates to the technical field of power distribution equipment, in particular to a remote control prepaid self-resetting low-voltage distribution box. Background technique [0002] Self-resetting overvoltage and undervoltage protection switch used in the distribution box. This kind of switch is red when the power supply is restored after a power failure. At this time, the switch is not connected, and the socket at home should be out of power, but the lighting is connected in front of this protection switch, so the lighting can be used normally. When the delay is 2-3 Minutes later, the indicator light turns green, and the internal relay of the protection switch is closed to supply power to the load. [0003] The existing electric low-voltage power distribution cabinets have the following defects: First, there is only one main box. In the case of limited capacity of the main box, in order to carry more electronic components, the ...

AI Technical Summary

Problems solved by technology

[0003] The existing electric low-voltage power distribution cabinets have the following defects: First, there is only one main box. In the case of limited capacity of the main box, in order to carry more electronic components, the electronic components are usually arranged more densely, so that Increased risk; second, for the distribution box with the addition of the auxiliary box, the main box and the auxiliary box usually need two heat dissipation systems to dissipate heat, which is inconvenient; third, the opening, closing and locking of the auxiliary box are generally more inconvenient
