Alarm power case

Abstract

The invention discloses an alarm power case. The alarm power case comprises a case door, a side wall, a top cover and a base which form a casing of the alarm power case, wherein the casing is provided with a blower fan top board, the blower fan top board is provided with a blower fan, and the blower fan top board is also provided with a plurality of fixation holes; the case door is provided with an alarm electromagnetic lock; the alarm electromagnetic lock comprises a housing, a control unit and an alarm unit; the electromagnetic control unit comprises a charge battery, a charge interface, a transformation module, a control switch, an electromagnet and a metal dead bolt; and the alarm unit comprises a power source, an alarm chip circuit, an alarm, a first contact sheet, a second contact sheet and a third contact sheet. The door lock of an alarm electric energy metering cabinet employs the electromagnetic lock, and the electromagnet is enabled to work through connection with the power source; the anti-theft performance is good, at the same time, the door lock can give an alarm when being abnormally open, and thus the purposes of frightening a thief and prompting an owner are realized; the charge battery is additionally arranged inside, and thus normal application of people during power failure is satisfied; and the structure is simple, the cost is low, the application is convenient, and thus wide promotion is facilitated.

Description

technical field [0001] The invention relates to the field of power distribution equipment, in particular to an alarm power box equipped with an alarm electromagnetic lock. Background technique [0002] The alarm power box is widely used in various electrical systems. At present, the heat dissipation of the alarm power box on the market is realized by the shutters around the box. However, when the frequency converter and soft starter are installed in the alarm power box, the heat generated is relatively large When the components are used, it is impossible to meet the requirements for the fan heat of these devices. Some alarm power boxes have ventilation holes on the top to achieve the purpose of heat dissipation, but this cannot prevent rainwater from entering the box. At the same time, it is also to prevent the electric energy meter from being damaged; to ensure the normal operation of the power system equipment, and also to prevent theft. And most of the existing electroma...
