Substation indoor environment intelligent control device

Abstract

The invention relates to a substation indoor environment intelligent control device which is characterized in that an indoor unit, an outdoor unit and a sensor set are included. The indoor unit comprises a box, an air inlet is formed in the upper portion of the box, an air outlet is formed in the lower portion of the box, the inside of the box is sequentially provided with an evaporator, a water collecting plate, a fan and a silencing pipeline from top to bottom, the evaporator corresponds to the air inlet in position, the water collecting plate is located under the evaporator, the upper end of the silencing pipeline is connected with the fan in a sealed mode, the lower end of the silencing pipeline is connected with the air outlet in a sealed mode, a controller is disposed in the box, a compressor is arranged in the outdoor unit, the sensor set comprises an outdoor temperature and humidity sensor and an indoor temperature and humidity sensor, and the evaporator, the fan, the compressor, the outdoor temperature and humidity sensor and the indoor temperature and humidity sensor are electrically connected with the controller. Environment control is performed on indoor space in a substation by means of the intelligent control device, potential safety hazards do not exist, energy can be saved, meanwhile, air outflow amount and air speed are easy to control, and eddies and turbulent flow can not be generated.

Description

technical field [0001] The invention relates to a control device, in particular to a device capable of intelligently controlling the temperature, humidity and air conditions of the indoor environment of a substation. Background technique [0002] With the rapid development of the national economy and smart grid construction, there are more and more substations of various voltage levels. In order to save precious land resources and reduce environmental problems such as noise and radiation, these substations are increasingly designed as Compact indoor arrangement, or placed underground. The closed nature of the environment makes the operating conditions of the electrical equipment in these substations very harsh, causing problems such as high indoor temperature and humidity, serious dust accumulation, poor ventilation, easy condensation of equipment, and excessive energy consumption. Environmental problems such as high temperature, humidity, dust, and noise erode the health o...

AI Technical Summary

Problems solved by technology

However, when the equipment is light-loaded or operated with a small load at night, it will cause unnecessary energy loss, and often cause excessive cooling, so that the humidity capacity of the air will drop or even reach saturation, and condensation will form on the surface of the equipment or insulator, causing discharge , flashover and other insulation faults, there are potential safety hazards

Since the air conditioner cannot fully achieve the purpose of dehumidification and anti-condensation, as the humidity in the switch cabinet increases, the electric heating rod is started when condensation occurs, but due to the improper installation position of the condensation sensor of the electric heater or the condensation sensor After the surface is eroded by dust and gas, the characteristics change, and the electric heating rod is often unable to be turned on in time, resulting in that the condensation in the cabinet cannot be treated in time

At the same time, the high temperature of the electric heating rod will cause accelerated aging of the adjacent electrical and insulators, which is not worth the loss, and will also cause energy loss.

[0005] Although sensing technology has been used to control the operation of the axial flow fan, its airflow configuration has not been considered in practical applications, so that most of the strong airflow generated by the high-power fan passes through the hall, and only a small part participates in the heat source surface. Heat exchange, part of which forms vortex and turbulent flow, becomes heat storage body and generates additional energy loss
