Wireless temperature measurement performance characteristics of switchgear

The wireless temperature measurement intelligent control device is a new type of multifunctional, intelligent dynamic simulation display and control device developed and designed based on the current development of medium and high voltage switchgear technology. It is suitable for various complete sets of devices such as central cabinets, handcart cabinets, fixed cabinets, and ring main units. It integrates functions such as contact/cable junction temperature measurement, three-phase temperature imbalance warning (optional), switchgear primary circuit simulation diagram, handcart (isolation knife) position, circuit breaker position (open/close status, spring energy storage status), grounding knife position, etc. It also has high-voltage live display (with self check), live locking, phase loss alarm, control and fault display of environmental temperature and humidity inside the switchgear, open/close, remote/local, manual/self storage control, cabinet lighting, RS485 communication, etc. This device not only has a beautiful and elegant appearance, but also optimizes the overall layout of the switchgear, making it an ideal replacement product for use in the new generation of switchgear.

Switch cabinetIntelligent wireless temperature measurement operationControl devicematters needing attention:

The power supply must be connected strictly according to the indicated voltage level, and the wiring must be strictly in accordance with the terminal markings on the back.

When installing, the wiring terminals should be tightened and the equipment should be firmly placed in a sturdy, fire-resistant, and vibration resistant position. The equipment works well when viewed from above, so it should be installed vertically at a height of 1.8m.

During the voltage withstand test, the terminals (20, 21, 22, 23) of the live display part must be disconnected or short circuited.

All switch contacts must be passive connections.

Connect according to the physical wiring label. Any changes will not be notified separately.
