Humidity automatic control system used for terminal box

Abstract

Provided is a humidity automatic control system used for a terminal box. The system comprises control storage equipment, a sensor group, display equipment and regulation and control equipment, whereinthe sensor group, the display equipment and the regulation and control equipment are electrically connected with the control storage equipment; the control storage equipment comprises a microprocessing chip, a data storage chip, a power amplifier and an operational amplifier, wherein the data storage chip, an input end of the power amplifier and an output end of the operational amplifier are electrically connected with the microprocessing chip respectively; the sensor group is electrically connected with an input end of the operational amplifier; the regulation and control equipment is electrically connected with an output end of the power amplifier; the display equipment is electrically connected with the microprocessing chip. By setting a threshold value and arranging a heating module and a refrigerating module, the humidity automatic control system used for the terminal box ensures that a heating module cannot cause an excessive temperature inside the box during the dehumidification process, and the intelligent regulation and control over the humidity inside the terminal box is achieved.

Description

technical field [0001] The present invention relates to the technical application field of terminal boxes, and more specifically, to an automatic humidity control system for terminal boxes. Background technique [0002] The terminal box is the transfer equipment for the control, protection, measurement, and metering circuit analog quantity extraction in the on-site operation equipment of the substation. It plays the role of connection transfer between the primary equipment and the secondary equipment, and is an important outdoor auxiliary equipment of the substation. In order to realize the intelligent control and stable power supply of the power system, it is necessary to ensure the safe and reliable operation of the outdoor terminal box. Terminal boxes are generally placed outdoors, which is obviously affected by the natural environment, especially in the Lingnan area where the weather is changeable. The operating environment of the terminal boxes installed in the outdoor ...
