Description

transformer respirator

technical field

The invention relates to a transformer respirator.

Background technique

As the main equipment in the power system, the safe and stable operation of the transformer directly affects the reliability of the power supply. As a part of the transformer, the respirator is generally composed of a silicone tank, an oil cup at the bottom center of the silicone tank, and a method at the top center of the silicone tank. Orchid composition. The silicone tube is composed of a glass tank body, the upper and lower end caps connected to the port of the glass tank body by bolts, the long bolts connected between the upper and lower end caps and passing through the tank body, and arranged between the glass tank body and the end caps. It consists of a sealing ring between the long bolts and the end cover; the upper end cover is provided with a silica gel injection and discharge port. The transformer respirator with this structure has the following problems: 1. Since there is only one silica gel injection and discharge port, when the silica gel deliquescence needs to be replaced, the oil cup must be removed first, and then the flange connection bolts on the top of the silica gel tank must be removed. Then turn the silica gel tank upside down so that the silica gel is discharged from the silica gel injection outlet, and the operation is cumbersome; 2. Since the sealing ring is opened during the disassembly process, the sealing effect will be affected when it is reinstalled, and it is easy to leak; 3. The long bolt is inserted into the silica gel tank. Pass through, the gasket provided at the connection between it and the end cap, the seal here is not good, which is easy to cause air leakage. 4. In winter, snow water is easy to flow into the oil cup from the outer wall of the silicone tank along the bottom surface of the lower end cover, and it is easy to crack the oil standard after freezing. 5. The height of the oil cup is 20mm-60mm. The oil in the oil cup is easy to absorb into the glass tank, and an oil film is formed on the surface of the silica gel, so that the silica gel loses its deliquescent effect.

Contents of the invention

The present invention aims to solve the above-mentioned problems in the prior art, and provides a transformer respirator.

Technical solution of the present invention is:

A transformer respirator, comprising a silicone tank, an oil cup set at the center of the bottom of the silicone tank, and a flange at the center of the top of the silicone tank, the silicone tank is made of a glass tank and connected to the port of the glass tank by bolts 1. The lower end cover is composed of long bolts connected between the upper and lower end covers and a sealing ring arranged between the tank body and the upper and lower end covers. The exhaust pipe at the bottom of the lower end cover is inserted into the oil cup. The special feature is : The upper and lower end caps are respectively provided with a silica gel injection port and a silica gel discharge port, and a sealing cover is installed on the silica gel injection port and the silica gel discharge port, the long bolt is located outside the glass tank, and the outer edge of the lower end cap is provided with a The water retaining edge, the height of the oil cup is 80mm-100mm.

The beneficial effects of the present invention are:

1. Due to the addition of a silica gel discharge port, the silica gel discharge port can be directly opened to discharge when replacing the silica gel, which is easy to operate and will not damage the original sealing structure, preventing the seal from being affected by the removal of the flange.

2. The long bolts are located outside the tank, which solves the problem of air leakage caused by poor sealing between the long bolts inside the tank.

3. The outer edge of the lower end cover is provided with a water retaining edge to prevent snow water from flowing into the oil cup from the outer wall of the silicone tank along the bottom surface of the lower end cover in winter, and the oil level will not freeze and crack.

4. The height of the oil cup is increased, so that the oil in the oil cup will not enter the tank when inhaling, so as to prevent the oil film from being formed due to the contact between the oil and the silica gel particles and lose the function of absorbing water and air.

Detailed ways

As shown in the figure, the transformer respirator includes a silica gel tank 1, an oil cup 2 located at the bottom center of the silica gel tank 1, and a flange 3 located at the top center of the silica gel tank 1; the silica gel tank 1 is made of a glass tank body 101 1. The upper and lower end caps 5, 6 connected to the port of the glass tank body 101 by long bolts 4 are formed by a sealing ring 8 arranged between the silica gel tank 1 and the upper and lower end caps; the bottom exhaust pipe 9 of the silica gel tank 1 Insert it into the oil cup 2 and keep a distance of 1cm-2cm from the inner bottom surface of the oil cup 2. On the upper and lower end covers 5 and 6, respectively set a silicone injection port 501 and a silica gel discharge port 601. The sealing cover 10, the long bolt 4 is located outside the silicone tank 1, the outer edge of the lower end cover 6 is provided with a water retaining edge 602 extending downward, and the height of the oil cup 2 is 80mm-100mm.

The top surface of the lower end cover 6 is a plane. In order to facilitate the discharge of silica gel particles, the top surface of the lower end cover 6 can be a slope inclined toward the silica gel discharge port 601.
