TEMPERATURE AND HUMIDITY INTELLIGENT SENSING UNIT OF DISTRIBUTING BOARD AND SYSTEM FOR INTELLIGENT SENSING TEMPERATURE AND HUMIDITY AND REMOTE AUTO CONTROLLING OF SWITCHGEAR AND AUTOMATIC PANEL}

The present invention relates to a temperature and humidity detection and control system, and more specifically, it is possible to easily detect the temperature inside the switchboard and the automatic control panel in any form through the rotation of a 180 degree temperature sensor, and also to detect the humidity. The present invention relates to a temperature and humidity detection and remote automatic control system of a switchboard and an automatic control panel that can be automatically controlled according to temperature and humidity.

In general, the distribution boards and automatic control panels have always been rated domestically approved voltages such as transformers, circuit breakers, capacitors, such as 22.9KV, 6.6KV, 3.3KV, 440V, 380 / 220V. In addition, the temperature rises by 10 ~ 30 ° C compared to the ambient temperature, such as heat generated by no load loss or load loss, heat generated by SOHO when the breaker is operated, heat generated by charge accumulation such as a capacitor, and heat generated by the intrinsic resistance when the electric device is operated.

In particular, the connection portion of the busbar is used for a long time or is gradually opened by vibration, which causes a problem that a poor contact may occur. When such a contact failure occurs, there is a problem that the motor does not operate normally due to the abnormal current.

There is a way.

However, such a temperature measuring method is very dangerous because the inspection of the busbar while energizing is exposed, and the burden of the inspection is actually generated because it may be directly connected to a large accident such as death due to a momentary mistake. Due to these difficulties, maintenance of the switchboard and the automatic control panel is inevitably neglected, and the switchboard and the automatic control panel operate normally, and there is a problem in that a substantial internal inspection is not performed unless an external problem occurs.

As shown in FIG. 5, the stopper 36 allows the sensor block 35 to rotate at a limited angle, for example 180 degrees. The stopper 36 generates a signal when the sensor block 35 is pressed, and sends the generated signal to the controller 60. By the signal received from the stopper 36, the controller 60 stops the operation of the sensor motor 33 and rotates the sensor block 35 in the opposite direction via the sensor motor 33.
