Background

The box-type transformer is designed in the box-type shell in a concentrated way, has small volume, light weight, low noise, low loss and high reliability, the box-type transformer is used as a whole set of power distribution equipment and is formed by organically combining a transformer, high-voltage control equipment and low-voltage control equipment. The basic principle is that a specific transformer is formed by reasonably assembling a pressure starting system, an armoured wire, a full-automatic transformer substation system, a direct current system and corresponding technical equipment according to a specified sequence and installing all components into a specific fully-sealed toughened box structure. Good internal environment of electrical equipment is an important factor for ensuring stable and safe operation of the equipment, and humidity, over-temperature and dust can cause equipment failure and even damage. The environment of the box-type transformer needs to be monitored and adjusted by using an environment integrated management device.

The common comprehensive management device for the environment of the box-type transformer is generally arranged in the box-type transformer and detects the inside of the box-type transformer through detection structures (such as a temperature detector, a dust content detector, a humidity detector and the like), when the environment change in the inside of the box-type transformer exceeds a certain range, an adjusting structure (such as a cooling fan, a ventilation fan and a heater) in the inside of the box-type transformer is started, and the environment in the inside of the box-type transformer is adjusted to perform comprehensive management. The traditional comprehensive management device for the environment of the box-type transformer is arranged in working environments such as open air and the like, when the environment meets humid weather, the air humidity is high, and the damage to the internal elements of the box-type transformer is easy to cause. For example, patent number CN214204600U is a box-type transformer with dehumidifying function, and the inside is heated and dehumidified by the cooperation of a sensor, an electric heating wire and a blower installed at the top of the inner cavity of the box-type transformer. However, in this way, since the moisture is usually located at the bottom of the cavity of the box-type transformer, and the blower continuously rises after bringing part of heat to the bottom of the cavity of the box-type transformer, the moisture of the box-type transformer cannot be comprehensively dehumidified, and therefore, the comprehensive environment management device for the box-type transformer is provided.
