Technical research on test method of the socket and switch of temperature monitoring alarm function

Abstract

The emergence of sockets and switches with fire protection monitoring and alarm functions had realized the forward detection of the fire risk monitoring gateway, which had played an important role in preventing the occurrence of electrical fires. In 2014, the national standard GB31252 “Fire Monitoring and Alarm Sockets and Switches” was promulgated and implemented, which detailed the product functions, performance and test methods of fire protection monitoring and alarm sockets and switches. This article is based on the difficulty of accurately controlling the heating process when measuring the temperature alarm value of the socket and switch. A new type of simulated temperature alarm test method was designed, and a detection device for the temperature test of the fire monitoring alarm socket and switch was developed. And the testing device was tested and verified. The test results show that the testing device designed in this paper can meet the technical requirements of the temperature part test in GB31252-2014.
