Price of wireless temperature measurement intelligent control device

Description :

　　With the increasing progress of municipal engineering renovation, the underground renovation of overhead insulated lines continues to increase. Most cables use rubber insulation. Although rubber has good insulation performance, with changes in the laying environment, rubber heating and aging lead to insulation breakdown of cables, which becomes a major obstacle in the process of electrical energy transmission. The prominent manifestation is that after the cable is laid underground for use, its operating condition cannot be visually detected, and the insulation aging, temperature rise, partial discharge and other problems of power cables after long-term operation lead to insulation breakdown. After a power cable failure occurs, finding the fault point becomes a major challenge for the power operation and maintenance department, which usually wastes a lot of manpower and material resources and brings incalculable power outage losses to the power department.

　　Design Scheme for Wireless Temperature Measurement SystemFrom the perspective of power supply methods, online temperature measurement can be mainly divided into two types: active temperature measurement and passive temperature measurement. Among them, active temperature measurement methods include infrared camera temperature measurement, which uses infrared imaging principles for real-time temperature detection, but the cost is very high; Passive temperature sensors mainly include platinum resistance temperature sensors, fiber optic temperature sensors, surface acoustic wave temperature sensors, and induction based temperature sensors.

　　The electrical contact wireless temperature measurement system is suitable for temperature monitoring of high-voltage switchgear contacts and contacts, knife switch switches, high-voltage cable intermediate heads, dry-type transformers, low-voltage high current equipment, etc. The device is designed with ultra-low power consumption technology and consists of an embedded integrated touch screen, wireless temperature measurement transceiver, and wireless temperature sensor. The wireless temperature sensor exchanges information with the host through wireless signal transmission, which does not affect the insulation performance of the system and is safer to use. The device has the characteristics of isolation, easy installation, strong anti-interference ability, and reliable operation, which solves the safety problem of contact temperature monitoring under high voltage conditions.

　　The Importance of Wireless Temperature Measurement System Design

　　The wireless temperature measurement system is a wireless measurement and easy to install temperature measurement system independently developed by our company. It adopts sensing technology and wireless communication technology for high-voltage isolation and signal transmission, utilizing its inherent insulation and anti electromagnetic interference performance to solve the problem of difficult monitoring of contact operating temperature inside high-voltage switchgear. This system is suitable for online temperature monitoring of various types of high-voltage equipment, with reliable high-voltage isolation, resistance to strong electric and magnetic field interference, and good thermal stability. The 10kV high-voltage cabinet is an indispensable part of the power system, and its safe operation is an important guarantee for user loads. The characteristics of high-voltage cabinets are high load current and thermal capacity, requiring regular temperature measurement. From a structural perspective, 10kV high-voltage cabinets can be divided into two types: rotary knife switch type and trolley type. The trolley type high-voltage cabinet has completely sealed contacts and cannot be observed for temperature measurement outside the cabinet. Therefore, inspectors can only indirectly calculate whether there is heat inside the cabinet by measuring the temperature, and the accuracy of temperature conduction loss is very low And it is impossible to observe subtle changes Not meeting the requirements for safe operation.

　　This wireless temperature measurement device system can detect abnormal heating faults by monitoring the temperature of hot spots such as switch contacts in real time, thereby preventing the occurrence of faults. Through temperature history records, it provides scientific data basis for "status maintenance" of switchgear. The safe operation of electrical equipment such as switchgear is of great significance.
