Transformer substation control box demisting system

Abstract

The embodiment of the invention discloses a transformer substation control box demisting system. The system is arranged on a collection control box. An observation window is arranged on the collectioncontrol box; the system includes a demisting detection device which is used for detecting whether mist exists on the observation window or not, and a mist removing device which is used for removing the mist on the observation window. The mist removing device comprises a mist removing assembly used for removing mist and a dew removing assembly used for removing dew. The demisting detection deviceis connected with the mist removing device; the mist removing device operates according to the data provided by the demisting detection device; whether the observation window fogs or not and the fogging condition can be intelligently judged, fog is removed when fog occurs, condensation is removed when condensation occurs, the observation window is kept clear, the observation effect of the observation window is guaranteed, meanwhile, condensation is removed in time, and it is avoided that secondary equipment in the box is affected due to the fact that the condensation is gathered in the box.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of substation safety, in particular to a defogging system for a central control box of a substation. Background technique [0002] There must be an observation window on the substation control box and mechanism box door for the on-duty staff to observe the indication position of the opening and closing indicator light, the energy storage status of the circuit breaker spring, the number of times the circuit breaker operates, and the indication of the opening and closing indicator board. During normal operation, the equipment in the HSBC box emits heat during operation, making the temperature inside the box higher than the temperature outside the box, and the lower the temperature, the lower the amount of water vapor that can be accommodated per unit volume of air, that is, the lower the saturated humidity of the air. When the air humidity exceeds the saturation humidity, the excess w...

Problems solved by technology

[0004] For this reason, the embodiment of the present invention provides a defogging system for the central control box of a substation to solve the problem that in the prior art, when the temperature difference between inside and outside the box is large, condensation fog is easily generated on the observation window, which affects the observation of the watchman. During the fogging time, the fog condenses into dew, which may also flow down to the bottom plate of the control box, affecting the insulation of the secondary equipment in the box
