Description

Temperature controller backplate isolating device

Technical Field

The utility model relates to a, in particular to temperature controller backplate isolating device.

Background

The capital airport power supply station is used as a guardian of an airport power grid and is currently responsible for maintaining 190 residual seats of a 10kV transformer substation, and due to different construction times, a 10kV system has the characteristics of large equipment quantity, wide distribution area, complex network structure and the like. The transformer is the most important component of 10kV primary equipment and plays an important role in an airport power grid. Because of gradual transformation and updating of equipment, more than 95% of transformers in the airport are dry-type transformers, and the dry-type transformers have the advantages of strong short-circuit resistance, small maintenance workload, high operation efficiency, small volume, low noise and the like.

At present, in order to guarantee the safety of operating personnel, the dry-type transformer all adopts shell and staff to carry out physical isolation, avoids staff and transformer distance too near and lead to the electric shock phenomenon. However, this does not facilitate better attention of the operator to the operation of the transformer. A very important indicator of whether a transformer is operating well is temperature, which is likely to cause a trip once the temperature rises. In the past, operating personnel adopt a temperature measuring instrument to measure the temperature of a transformer, so that the operating condition of the transformer can be known to a certain extent, but the operating condition is not comprehensive enough. Along with the development of science and technology, have more audio-visual understanding for better to the transformer operating mode, save operating personnel's labour simultaneously, adopt the temperature controller to detect the transformer temperature. The working principle is that the ambient temperature is automatically sampled and monitored in real time through the temperature sensor, and when the ambient temperature is higher than a control set value, the control circuit is started, so that a control return difference can be set. If the temperature is still rising, the overrun alarm function is started when the temperature rises to the set overrun alarm temperature point. When the controlled temperature cannot be effectively controlled, the equipment can be stopped to continue to operate through a trip function in order to prevent the equipment from being damaged.

At present, the temperature controller needs to have a power failure operation to the transformer in the installation, and the installation is also consuming time longer, makes airport electric wire netting work unstable during the installation easily.
