Electric energy meter with sealing and dustproof performance

Abstract

The invention discloses an electric energy meter with sealing and dustproof performance, which belongs to the technical field of electric energy meters and comprises a mounting plate, an electric meter body is fixedly mounted on the mounting plate, a wiring board is integrally formed at one end of the electric meter body, a wiring mechanism is mounted at the wiring board, an outer cover is hinged to one side of the mounting plate, and vent holes are formed in two sides of the outer cover. A sealing mechanism is installed on the inner wall, close to the ventilation hole, of the outer cover, a dustproof mechanism is installed on the outer wall, close to the ventilation hole, of the outer cover and connected with the sealing mechanism, and a thermal driving mechanism is installed on the inner wall of the outer cover. Line connection is carried out through the wiring mechanism to achieve a protection effect, the outer cover completely wraps the electric meter at ordinary times, when the temperature of the electric meter body is low, the sealing mechanism blocks and seals the ventilation hole to completely isolate external dust, and when the temperature in the outer cover is increased due to temperature rise of the electric meter body, the thermal driving mechanism drives the sealing mechanism to be opened, and the ventilation hole is unblocked. Ventilation and heat dissipation are achieved through the ventilation holes, and dust prevention is achieved through the dustproof mechanism.

Description

technical field [0001] The invention relates to the technical field of electric energy meters, in particular to an electric energy meter with sealing and dustproof performance. Background technique [0002] The watt-hour meter is referred to as the watt-hour meter for short. It is an instrument used to measure electric energy, also known as the watt-hour meter, fire meter, watt-hour meter, and kilowatt-hour meter. It is connected with the electric shock of the electric energy meter. The electric energy meter is directly exposed. After a long time, it is easy to cause dust accumulation on the electric energy meter, especially when the dust accumulation on the terminal is easy to affect the conductivity. At present, some electric energy meters are installed on the outside when they are installed. The protective cover is used for protection, which not only avoids dust accumulation, but also prevents electric shock. However, after the simple protective cover is sealed, it will a...

Problems solved by technology

[0002]The electric energy meter is referred to as the electric meter for short. For measuring instruments, the current electric energy meter wiring is connected with the electric shock of the electric energy meter through screws, and the electric energy meter is directly exposed, which will easily lead to dust accumulation on the electric energy meter after a long time, especially when the dust accumulation on the terminal is easy to affect Electrical conductivity. At present, when some electric energy meters are installed, a protective cover will be installed on the outside for protection, which not only avoids dust accumulation, but also prevents electric shock. However, after the simple protective cover is sealed, it will affect the heat dissipation of the electric energy meter during operation, resulting in electric energy. The high temperature operation of the meter will affect the service life of the electric energy meter. Therefore, we propose an electric energy meter with sealing and dustproof performance to solve the above problems
