Anti-theft dampproof ammeter

Abstract

The invention discloses an anti-theft dampproof ammeter. A protection device for shielding a transparent glass window in a tank cover is arranged on an ammeter tank body; the protection device comprises a transverse moving locking buckle plate, a shielding plate, a traction electromagnet and a return spring; the traction electromagnet is electrified to control a moving block to move downwards; theshielding plate is clamped inside a rectangular insert hole of the transverse moving locking buckle plate; the transverse moving locking buckle plate is used for locking the shielding plate; the moving block is moved upwards after the traction electromagnet is cut off from power; the shielding plate is dissociated from the rectangular insert hole of the transverse moving locking buckle plate; atthe moment, the shielding plate can be opened, and the traction electromagnet is connected with a controller; and the controller is connected with a mobile control terminal through a wireless transceiver. The ammeter can be opened by using a special control terminal, and thus the ammeter can be prevented from being stolen. The anti-theft dampproof ammeter is simple in structure and convenient to mount.

Description

technical field [0001] The invention relates to the technical field of electric power, in particular to an anti-theft and moisture-proof electricity meter. Background technique [0002] Municipal, residential, electric power, rural power grids, factories and other places with public facilities need to install ammeters, which also require ammeter boxes. However, the existing ammeter boxes containing ammeters usually use transparent materials such as glass and plastics to make observation windows, which can be broken by criminals to steal electricity and bring losses to the public interest. In addition, after the traditional meter box is used for a long time, water and moisture will easily flow into the meter from the connection between the box body and the cover of the meter box, so that the meter will easily conduct electricity after being damp, which poses a great safety hazard and has a short service life.

Problems solved by technology

However, the existing electric meter boxes for containing electric meters usually use transparent materials such as glass and plastics to make observation windows, which can be broken by criminals to steal electricity and bring losses to the public interest.

In addition, after the traditional meter box is used for a long time, water and moisture are easy to flow into the meter from the connection between the box body and the box cover of the meter box, so that the meter is easy to conduct electricity after being damp, which poses a great safety hazard and has a short service life.
