Description

A box-type transformer temperature and humidity measurement and control device

Technical Field

The utility model relates to the technical field of electric power equipment, in particular to a temperature and humidity measuring and controlling device for a box-type transformer.

Background Art

As the manufacturing cost of wind turbines decreases, the capacity of a single onshore wind turbine reaches 5MW, and the box-type transformers that match it need to be equipped with differential protection measurement and control devices (hereinafter referred to as comprehensive protection devices) to achieve low-voltage protection tripping and remote automation control of the box-type transformer. At present, the comprehensive protection device is installed in the secondary compartment of the box-type transformer during production and manufacturing, and is in a closed box with the box-type transformer body. DLT587-2016 "Regulations on the Operation and Management of Relay Protection and Safety Automatic Devices" stipulates that for microcomputer protection devices installed in prefabricated cabins, the temperature is required to be within the range of 5℃ to 30℃.

The existing equipment has the following shortcomings: in the hot and windy weather in summer, when the wind turbine is in a high-load power generation state, the temperature of the transformer body usually reaches 80°C. Due to the thermal conductivity of the iron plate, the temperature of the secondary compartment also reaches 80°C, which far exceeds the allowable operating temperature requirement of the comprehensive self-protection, causing the comprehensive protection device to be damaged due to high temperature failure.

Therefore, the present application now proposes a box-type transformer temperature and humidity measurement and control device to solve the above-mentioned problems.

Utility Model Content

The utility model aims to provide a temperature and humidity measuring and controlling device for a box-type transformer, so as to solve the problem that the above-mentioned comprehensive protection device is damaged due to high temperature failure.

Wherein, the rotating plate is arranged in an L shape.

Wherein, the sensing devices are symmetrically arranged at eight inner corners of the box body.

Wherein, one of the sensing devices includes a temperature sensor arranged on the inner wall of the box and a humidity sensor arranged on the inner wall of the box and close to the temperature sensor.

Wherein, a triangular top cover is arranged on the top of the box body, exhaust ports are opened on both sides of the box body, and an air filter is arranged on the side wall of the box body.

Compared with the prior art, the beneficial effects of the utility model are:

1. The box body of the utility model adopts 2mm thick stainless steel and adopts a double-layer door panel design. The outer shell of the box body is coated with light white anti-rust paint to reflect sunlight. A terminal block is installed inside the box body. The perforated panel is used for the installation of the comprehensive protection device and the secondary circuit access. The comprehensive protection device is installed and fixed on the perforated panel. The secondary wiring is between the comprehensive protection device and the terminal block. The installation hole is opened in the double-layer box door for installing the embedded air conditioner.

The air conditioner is used to automatically adjust the temperature and humidity in the box body to within the set range. The sensing device can monitor the humidity and temperature inside the box body. When the temperature and humidity exceed the normal range, the sensing device turns on the air conditioner to cool or dehumidify the inside of the box body. The wind direction adjustment unit can adjust the direction of the cold air blown by the air conditioner so that the cold air can be air-cooled and dissipated to the rear side of the comprehensive protection device inside the box body, thereby improving the cooling efficiency of the working components inside the box body.

2. The cold air of the air conditioner of the utility model enters and exits the interior of the box in the direction shown in Figure 5, and then the cold air passes through the rotating plate and is redirected after being blocked by the rotating plate. The vertical cold air can be changed into horizontal air, and then the rear side of the comprehensive protection device can be cooled and dissipated. When the temperature inside the box is high, the hydraulic cylinder can adjust the installation angle of the rotating plate so that the horizontal plate of the rotating plate rotates toward the side of the rear wall of the comprehensive protection device inside the box, so that the rotating plate gathers the cold air blown out by the air conditioner to one side of the rear wall of the comprehensive protection device, thereby accelerating the heat dissipation efficiency of the cold air to the comprehensive protection device. When the stability inside the box is not very high, the rotating plate can make the cold air blown out by the air conditioner blown more evenly on the rear wall of the comprehensive protection device, thereby increasing the heat dissipation area of the rear wall of the comprehensive protection device.

The sensing device 5 is arranged inside the box 1 and is used to detect the humidity and temperature inside the box 1 .

It should be noted that, when working, the box 1 is made of 2mm thick stainless steel and a double-layer door panel design. The outer shell of the box 1 is painted with light white anti-rust paint to reflect sunlight. A terminal block is installed inside the box 1. The perforated panel is used for the installation of the comprehensive protection device and the access to the secondary circuit. The comprehensive protection device is installed and fixed on the perforated panel. The secondary wiring is between the comprehensive protection device and the terminal block. An installation hole is opened in the double-layer box door 2 for installing the embedded air conditioner 3. The drainage pipe of the air conditioner 3 is laid vertically along the door panel without affecting the equipment maintenance. PP-R environmentally friendly water pipes are selected. The air conditioner 3 is used to automatically adjust the temperature and humidity in the box 1 to within the set range. The sensing device 5 can monitor the humidity and temperature inside the box 1. When the temperature and humidity exceed the normal range, the sensing device 5 turns on the air conditioner 3 to cool or dehumidify the interior of the box 1. The wind direction adjustment unit 4 can adjust the direction of the cold air blown out by the air conditioner 3, so that the cold air can be air-cooled and dissipated to the rear side of the comprehensive protection device inside the box 1, thereby improving the cooling efficiency of the working components inside the box 1.
