Electric metering device with shock-proof function

Abstract

The invention discloses an electric metering device with a shock-proof function. The device comprises a cabinet body, a sliding block, a fixed base, a first protective cover and a second protective cover; a cabinet door is arranged on the cabinet body, an electric meter is arranged on a fixed mounting aluminum plate, and sliding blocks are arranged at two sides of the cabinet body; the fixed baseis fixedly welded on the bottom end of a cooling column, a sliding rod penetrates from the sliding block; the first protective cover and the second protective cover are respectively welded on the cabinet body and the cooling column; the radiating top cap is connected with the cabinet body top end through a spring, and the fixed base is connected with the bottom end of the cabinet body through thespring; and a ponding slot is arranged below a water baffle plate. The electric metering device is provided with the cooling column and a cooling top cap, the heat in the cabinet body emits into the air from cooling through holes on the cooling top cap through the cooling column; in the rainy day, the rainwater entering from the cooling through holes can drop into the ponding slot, thereby preventing the rainwater from entering the internal of the cabinet body while in the cooling, and guaranteeing the normal running of the electric meter.

Description

technical field [0001] The invention relates to an electric power equipment, in particular to an electric power metering device with shock resistance. Background technique [0002] The ammeter used for power metering is usually installed inside a fixed meter box. Heat is generated during the operation of the ammeter. In order to ensure the normal operation of the internal components of the ammeter, the heat needs to be discharged, so a ventilation structure is required. [0003] Existing power metering devices have cooling holes on the top of the box to dissipate heat through the cooling holes, but in rainy days, rainwater easily enters the inside of the box through the cooling holes, which is likely to cause a short circuit of the electric meter and pose a safety hazard. The existing box body does not have a shock absorption function. When there is a violent vibration on the ground, it is easy to cause damage to the electric meter, and the practicability is not strong. In v...

Problems solved by technology

[0004] In view of the above situation, the technical problem to be solved by the present invention is that in rainy days, rainwater easily enters the inside of the box body through the heat dissipation holes, which easily causes the short circuit of the electric meter and has potential safety hazards. When severe vibration occurs, it is easy to cause damage to the meter, and the practicability is not strong
