Abstract

The invention provides a temperature control alarming system of a large-power electrodeless lamp ultraviolet radiation cavity and a temperature control alarming method of the temperature control alarming system, and relates to the technical field of ultraviolet crosslinking. The system and the method solve the problems that when an existing ultraviolet crosslinking high-voltage cable works, the temperature cannot be obtained and temperature ranges cannot be controlled. The system forms a closed loop through a temperature sensor, a signal adjustment amplification and multi-channel data collection unit, a blower, a suction fan and a control unit, so the temperature of a large-power magnetic control tube can be obtained in real time when the large-power electrodeless lamp ultraviolet radiation cavity works, the temperature is regulated through the blower, the suction fan and the control unit, and the alarming purpose is achieved through an audible and visual alarm. According to the method, control is achieved according to changing trends of the temperature maximum value of detected temperature points at a certain moment and the temperature maximum value of the detected temperature points at the next moment, control of the temperature of the electrodeless lamp ultraviolet radiation cavity is achieved, and operators can conveniently and timely maintain the system through the audible and visual alarm. The system and the method are suitable for the technical field of the ultraviolet crosslinking.

Description

technical field [0001] The invention relates to a temperature control and alarm system for a high-power electrodeless lamp ultraviolet irradiation cavity and a temperature control and alarm method thereof, in particular to the technical field of ultraviolet crosslinking. Background technique [0002] It is well known that UV light can crosslink polyethylene materials. In recent years, with the development of ultraviolet cross-linking technology and high-power ultraviolet electrodeless lamps, ultraviolet cross-linking technology has been applied to more and more fields, and long-length high-voltage cables are one of them. [0003] Ultraviolet light cross-linking cable technology is to irradiate polyolefin materials with high-intensity ultraviolet light and add photoinitiators, multifunctional crosslinking agents, etc. to strengthen the photoinitiation system. Free radicals are formed and a photocrosslinking reaction occurs, transforming the polyolefin into a crosslinked mate...
