A fire monitoring device and monitoring method for a power metering box

Abstract

The present disclosure proposes a fire monitoring device and monitoring method for a power metering box. The monitoring device includes a signal detection device, an analog-to-digital signal conversion module, a control unit, and an actuator. The signal detection device is connected to the analog-to-digital conversion module. The analog-to-digital conversion module and the actuator are respectively connected with the control unit; the signal detection device includes a temperature sensor, and the temperature sensor is arranged at the switch of the power metering box. A tripping device, a fire extinguishing device and a switch control module are also set up. By setting the graded control threshold, graded control is realized according to different temperatures, which can switch the fire monitoring device to a dormant state, control the power metering box's internal circuit power-off and When a fire occurs, the fire is extinguished, and the temperature sensor is set at the switch, so that abnormal heating can be detected in time, so that the trigger point of the fire can be found in time, and corresponding measures can be taken in advance to prevent 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
