Technical Field
[0001] The utility model relates to the field of electric power metering boxes, in particular to a fire extinguishing protection mechanism of an electric power metering box. Background Art
[0002] The power metering device is a metering instrument used to measure and record the amount of power generated, the amount of power supplied (mutually supplied), the amount of power consumed by the factory, the amount of power lost and the amount of power consumed by the user. The power metering device refers to the whole composed of the power meter (active power meter, reactive power meter, maximum demand meter, multi-rate power meter, etc.), the metering transformer (including voltage transformer and current transformer) and the secondary connecting wire. The staff needs to protect the power metering equipment. The existing power metering equipment protection peripherals are mostly fixed outdoors. In summer, the outdoor temperature is too high, the power consumption of users increases sharply, and the load of the power metering box also increases. Fires may occur due to untimely heat dissipation or aging of the lines. When the maintenance personnel receive the fire information and go to the scene to extinguish the fire, this process will miss the best time for disaster relief. Therefore, a device is needed to extinguish the fire in time when the power metering box catches fire.

[0006] In the above manner, when a fire occurs, the limit device cancels the lock on the mobile fire extinguishing device, and under the action of the ejection device, the mobile fire extinguisher moves up and down and sprays dry powder to extinguish the fire.
[0007] Furthermore, the mobile fire extinguishing device includes: a T-shaped block, a slide plate and a dry powder fire extinguisher. A vertical main slide is provided on the partition shell.
