Fire protection monitoring device and monitoring method of electric meter box

Abstract

The invention proposes a fire protection monitoring device and monitoring method of an electric meter box. The monitoring device comprises a signal detection device, an analogue-to-digital signal conversion module, a control unit and an execution mechanism, wherein the signal detection device is connected with the analogue-to-digital signal conversion module, the analogue-to-digital signal conversion module and the execution mechanism are connected with the control unit, the signal detection device comprises a temperature sensor, the temperature sensor is arranged a switch of the power meter box, a trip device, a fire extinguishing device and a switch control module are further arranged, hierarchical control is achieved by setting a hierarchical control threshold according to different temperatures, the first protection monitoring device can be switched to a dormant state, an internal circuit in the electric meter box is controlled to be powered off, and fire is extinguished when fireoccurs; and moreover, the temperature sensor is arranged at the switch, abnormal heating can be timely found out, so that a fire trigger point can be timely found out, and a corresponding measure is taken in advance to prevent the fire.

Description

technical field [0001] The present disclosure relates to the technical field related to electric power equipment, and in particular, relates to a fire monitoring device and a monitoring method for a power metering box. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] The metering box with a metal shell should be insulated, and leakage and electric shock accidents often occur. Most of the metering boxes currently in use are flame-retardant non-metallic plastic metering boxes. The use of plastic metering boxes reduces the occurrence of electric shock accidents, but in The high temperature season in summer has brought great fire hazards. According to statistics, there are cases of metering boxes and meters being burned every summer, and the number of occurrences is relatively large, which not only has a great impact on the majority of users,...

Problems solved by technology

[0003] The metering box with a metal shell should be insulated, and leakage and electric shock accidents often occur. Most of the metering boxes currently in use are flame-retardant non-metallic plastic metering boxes. The use of plastic metering boxes reduces the occurrence of electric shock accidents, but in The high temperature season in summer has brought great fire hazards

According to statistics, there are cases of metering boxes and meters being burned every summer, and the number of occurrences is relatively large, which not only has a great impact on the majority of users, but also brings great losses and negative effects to the power supply company.

In view of the burning problem of metering boxes and meters, this disclosure proposes a fire monitoring device for electric metering boxes to protect the metering boxes and meters from fire
