Embodiment Construction
[0009] The present invention will be described in detail below in conjunction with accompanying drawing: figure 1 As shown, the present invention includes a power meter box 1 mainly composed of an air switch, and on both sides of the air switch 2 inlet and outlet lines on the user side of the power meter box 1, the exposed electrified body is effectively isolated from the outside world. The plexiglass cover 3 is installed on both sides of the air switch inlet and outlet lines on the user side and on the plexiglass cover 3 are two LED live display lights 5 that are in contact with the electrified body 4, so that users who do not have an electroscope pen can clearly understand whether their own incoming line switch has Electricity.
[0010] The plexiglass cover 3 is at least made up of a side plate 31 fixedly connected to the box plate of the power meter box 1 and a cover panel 33 hinged by a rotating shaft 32, at least one side of the side plate 31 and the cover panel 33 are hi...

The invention discloses an electrified detection device of low-voltage equipment. The electrified detection device comprises a power meter collecting box which mainly comprises an air switch, wherein the line incoming side and the line outgoing side of the air switch on a user side of the power meter collecting box are provided with organic glass covers for effectively isolating an electrified body exposed outside and the outside; two LED (Light Emitting Diode) electrified displaying lamps in contact with the electrified body are arranged on the line incoming side and the line outgoing side of the air switch on the user side and on the organic glass covers, so that a user without an electroscopic pen can clearly know whether an own line-incoming switch is electrified; each organic glass cover at least comprises a side plate fixedly connected to a box plate of the power meter collecting box and a cover panel hinged by a rotating shaft; at least one side edge of the hinged position of the side plate and the cover panel is provided with pressing type locking fasteners, one end of each pressing type locking fastener is fixed on the side plate, and the other end of each pressing type locking fastener is fastened on the cover panel; the inner side of the cover panel is provided with the LED electrified display lamps. The electrified detection device disclosed by the invention has the characteristics that the structure is simple, the use is convenient and reliable, the power failure can be effectively judged by a user, the working efficiency of rush power repair can be improved and the like.
Description
technical field [0001] The invention relates to a live monitoring device for low-voltage equipment, in particular to a live monitoring device for a power meter box in a residential quarter, and belongs to the technical field of operation and maintenance of low-voltage power equipment. Background technique [0002] In the prior art, the power meter box used in residential buildings includes the air switch of the resident user. When a fault occurs, the resident user cannot judge the type and scope of the fault by himself, so he calls 95598 for repair. Emergency repair personnel can only go to the scene to check and measure with an electroscope on the upper part of the user's air switch (incoming line side). If it shows that there is power, the fault type belongs to the user's internal line fault, which is not the scope of the power bureau's work; if it shows no power, it is a fault. System equipment failure, commonly known as external line failure, belongs to the scope of work...
