Passive wireless temperature measurement price

Description :

　　The application and promotion of wireless temperature measurement devices in ring main units is a trend and a major achievement of innovation. The application of the Ankerui wireless temperature measurement device introduced in this article in the ring main unit can achieve the integration of operation and display, and can monitor the temperature incoming lines of the busbar, circuit breaker upper and lower contacts, cable joints, etc. in the cabinet online. It can prevent the risk of overheating caused by excessive contact resistance due to oxidation, loosening, dust and other factors during operation, improve equipment safety guarantee, timely, continuously and accurately reflect the operating status of the equipment, avoid safety accidents, and reduce equipment accident rate.

　　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.

　　With the progress of economic globalization, the development of the power grid system is very rapid, and traditional supporting facilities can no longer meet the needs of the power grid. The increasing burden on the power grid has raised higher requirements for the quality of ring main units. After long-term use, the ring main unit may experience slow equipment operation, insensitive response, and difficult temperature control, which reduces the lifespan and safety guarantee of the ring main unit. Due to the high temperature in summer, as the amount of heat absorbed by the ring main unit increases, the burden will also increase. The increased charge in the power grid system causes the temperature to rise rapidly. If the temperature detection system cannot respond in a timely manner, it may quickly damage the ring main unit and even cause accidents such as fire and leakage. Incomplete installation of temperature measuring devices can increase the incidence of accidents. Overloading or using temperature measuring devices beyond their lifespan can greatly reduce their sensitivity and have a negative impact on testing. With the acceleration of urbanization, the huge amount of electricity transmission during peak periods has brought a great burden to the ring main unit. Ring main units are often installed in spacious outdoor areas, in direct contact with the outside world, and are subject to long-term rainwater erosion, which accelerates equipment corrosion. Long term exposure to high temperatures outdoors or excessive use can increase the incidence of equipment failure.

　　In response to the problem caused by high temperature in the ring main unit, in order to provide safety and reliability of power supply, Ankerui has launched a temperature monitoring product for electrical connection points inside the ring main unit. It can monitor the temperature of electrical connection parts such as copper bars, cables, and circuit breaker plum blossom contacts in the cabinet in real time, facilitating the operation and maintenance of the entire distribution room. The following is the selection plan for temperature measurement products of electrical nodes in switchgear.

　　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.
