Online Temperature Measurement Device for Electrical Contacts

The SMR-EJWT series online temperature measurement device for electrical contacts is an intelligent device used in high, medium, and low voltage power systems (110kV, 6～35kV and 0.4kV) and for electrical contact equipment with high temperature requirements. It is a modern high-tech product integrating online temperature measurement, data acquisition, data analysis, and control functions.

(1) Instrument control terminal with data display and setting functions; local viewing of operating status and setting of operating parameters are possible.

(2) Temperature data acquisition unit, equipped with 3/6/9/12 channels.

(3) Employs multiple anti-interference measures, ensuring stable operation in power systems.

(4) Uses a self-locking panel mounting mechanism; small size and easy installation.

(5) Simple and user-friendly system wiring.

(6) Large-size dedicated LCD module; intuitive display, user-friendly operation, and simple operation.

High Precision and High Reliability: Employs a high-precision digital temperature chip, with measurement accuracy typically reaching ±1°C, ensuring accurate and reliable data.

Truly Maintenance-Free: Passive sensor design, with a theoretical lifespan identical to that of the power equipment, requiring no battery replacement or maintenance throughout its entire lifespan.

Strong Anti-Interference Capability: Utilizes 2.4GHz ZigBee/LoRa wireless communication technologies, featuring frequency hopping and retransmission mechanisms, ensuring stable data transmission even in switchgear environments with strong electromagnetic interference.

Real-Time Alarm and Warning: Multiple temperature thresholds can be set (e.g., warnings, alarms). When the temperature exceeds the limit, immediate alarms are triggered via indicator lights on the device itself, audible and visual signals from the backend system, and SMS messages.

Data Recording and Analysis: The device can record historical temperature data and alarm events long-term, facilitating trend analysis, early detection of potential faults, and a shift from "reactive maintenance" to "predictive maintenance."

High-Voltage Switchgear: Busbar connections, stationary contacts, circuit breaker upper and lower terminals, etc.

GIS (Gas Insulator System): A crucial connection point between the conductors on both sides of the basin-type insulator.

Outdoor disconnectors and line connectors: Solve the problem of temperature measurement difficulties for outdoor equipment through wireless transmission.

Wind/PV substations: Monitor the temperature of critical electrical nodes such as combiner boxes and transformer substations.

Power distribution systems in industries with extremely high requirements for power supply continuity, such as steel, chemical, and data centers.
