Skid-mounted transformer device and using method thereof

Abstract

The invention discloses a skid-mounted transformer device, which comprises a skid body, wherein the skid body is divided into a transformer chamber and a security control chamber by a partition plate,a transformer body is arranged in the transformer chamber, an oil collecting pool is arranged at the lower end of the transformer body, a bus system and a transformer radiator are further connected to the transformer body, the bus system extends out of the skid body to be connected with an external wire, and the transformer radiator extends out of the skid body through a pipeline; a control system and a gas fire extinguishing system are arranged in the security control chamber, a fire alarm system, an intelligent ventilation system, a heating system and a dehumidification system are further arranged in the skid body, and the transformer radiator, the gas fire extinguishing system, the fire alarm system, the intelligent ventilation system, the heating system and the dehumidification systemare all electrically connected with the control system. The device is suitable for various severe environments, the service life of a transformer substation is effectively protected, the precision and automation degree of temperature and humidity monitoring control are high, and various costs can be greatly reduced.

Description

technical field [0001] The invention provides a skid-mounted transformer device and a method for using the same, belonging to the technical field of mobile power transmission and distribution. Background technique [0002] At present, the power transformers used in various power system substations in metallurgy, petroleum, chemical industry, coal, steel, electric power and other industries are mostly placed in the open air environment, with poor protection effect, and are greatly affected by the harsh outdoor environment. Transformers installed outdoors have a series of problems such as anti-condensation, lightning protection, anti-sunlight, anti-pollution, and anti-corrosion. The service life is relatively short, the reliability is low, and the replacement frequency is high, which affects the normal operation of the lower-level power distribution equipment.

Problems solved by technology

[0002] At present, most of the power transformers used in substations of power systems in industries such as metallurgy, petroleum, chemical industry, coal, steel, and electric power are placed in outdoor open-air environments with poor protection effects and are greatly affected by harsh outdoor environments.

Transformers installed outdoors have a series of problems such as anti-condensation, lightning protection, anti-sunlight, anti-pollution, and anti-corrosion. The service life is relatively short, the reliability is low, and the replacement frequency is high, which affects the normal operation of the lower-level power distribution equipment

In order to solve the problems referred to above, those skilled in the art have thought of mainly carrying out two kinds of technical transformations to substations. 1. Skid-mounted technical transformations, such as CN109861119A, CN208015202U, CN208939339U and other Chinese disclosed patents all disclose skid-mounted substation structures. The design of skid-mounted transformation only does not involve the monitoring and control of the environment, which partially solves the above problems, but for some extremely harsh environments, such as ultra-high temperature, ultra-low temperature, and high humidity environments, the above-mentioned problems cannot be solved well. ; 2, house-type technical transformation, such as CN208521198U, C105424088A and other Chinese disclosed patents all disclose the house-type electric house structure, which also partially solves the above-mentioned problems, but the house is a fixed model, and the cost of setting up is relatively high, so it is not suitable for convertible The mode of time and place, especially in places where the geographical environment is relatively harsh, and its working principle only considers indoor temperature monitoring, and is not suitable for the harsh environment in the field, and its monitoring accuracy is low during construction, and the construction cost is high.
