Description
Technical field
The utility model relates to the compensation of volume variation and temperature control devices, and specifically a kind of is that transformer and electric power are set
The inner oil type metal bellow oil conservator with limit decompression function that standby configuration uses.
Background technique
Existing internal metal bellow expansion oil conservator uses stainless steel ripple core as cubage compensation element, complete
Completely cut off under conditions of air and moisture, is connected to by pipeline road with oil tank of transformer.When insulating oil temperature change, corrugated core
Body expansion or shrinkage therewith, to realize the volume compensation to insulating oil.
And will appear phenomenon of rushing to summit often due to the flexible nature of core, during present oiling, cause entire oil conservater
It scraps.
Utility model content
In order to solve the problems, such as that existing core causes whole oil conservater to be scrapped during oiling because rushing to summit phenomenon,
The purpose of this utility model is to provide a kind of inner oil type metal bellow oil conservators with limit decompression function.
The purpose of this utility model is achieved through the following technical solutions:
The utility model includes cabinet body and is installed on the intracorporal wavy metal expanding core body of the cabinet, and the wavy metal expands
The upper surface of core is equipped with binary channels stroke valve, and the inside of the binary channels stroke valve is interior with the wavy metal expanding core body
Portion is connected, and goes up and down with the expansion or shrinkage of wavy metal expanding core body；Two interfaces point on the binary channels stroke valve
Be not connected with relief tube and exhaust pipe, the relief tube and exhaust pipe are separately mounted on cabinet body, one end respectively with the binary channels
The interface of stroke valve is connected, and the other end is communicated with the atmosphere；Pipeline road is installed, wavy metal expanding core body is logical on the cabinet body
Pipeline road is crossed to be connected to the fuel tank of transformer；
Wherein: the binary channels stroke valve is bi-bit bi-pass servomotor driven change valve, the moving direction of valve head and the metal
The short transverse of ripple expanding core body is in the same direction；
The relief tube and exhaust pipe are divided into two sections, wherein one section is the hard tube being installed in the cabinet floor, separately
One end is the bellows for being connected to interface on hard tube and the binary channels stroke valve；
Cabinet cover limit plate is installed on the cabinet body inner wall above the binary channels stroke valve；
The exhaust pipe is normally open, and the relief tube is normally off.
The advantages of the utility model and good effect are as follows:
1. the utility model is provided with binary channels stroke valve, during oiling, bilateral on wavy metal expanding core body
Road stroke valve rises with wavy metal expanding core body, can be opened by the contact with cabinet cover limit plate, carries out pressure release, draining,
Avoid rushing to summit the generation of phenomenon, extends the service life of oil conservater.
2. the relief tube and exhaust pipe that connect on the binary channels stroke valve of the utility model, having one section is bellows, is kept away
Exempt to be easily broken off because of rigid connection.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model；
Wherein: 1 is relief tube, and 2 be exhaust pipe, and 3 be binary channels stroke valve, and 4 be pipeline road, and 5 expand for wavy metal
Core, 6 be cabinet body.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
As shown in Figure 1, the utility model includes cabinet body 6 and the wavy metal expanding core body 5 that is installed in the cabinet body 6,
The upper surface of middle wavy metal expanding core body 5 is equipped with binary channels stroke valve 3, which is that bi-bit bi-pass is motor-driven
Reversal valve, inside is connected with the inside of wavy metal expanding core body 5, with the expansion or shrinkage of wavy metal expanding core body 5
Lifting, the valve head moving direction and the short transverse of wavy metal expanding core body 5 of binary channels stroke valve 3 are in the same direction.
Two interfaces on binary channels stroke valve 3 are connected separately with relief tube 1 and exhaust pipe 2, the relief tube 1 and exhaust pipe
2 are separately mounted on cabinet body 6, and one end is connected with the interface of binary channels stroke valve 3 respectively, and the other end is communicated with the atmosphere.This is practical
Novel relief tube 1 and exhaust pipe 2 is divided into two sections, wherein one section is the hard tube being installed on 6 bottom surface of cabinet body, the other end is to connect
Pass through the bellows of interface on hard tube and binary channels stroke valve 3.It is equipped on 6 inner wall of cabinet body above binary channels stroke valve 3
Cabinet cover limit plate, valve head are contacted when wavy metal expanding core body 5 runs to extreme position with cabinet cover limit plate.
Pipeline road 4 is installed, wavy metal expanding core body 5 is connected by the fuel tank of pipeline road 4 and transformer on cabinet body 6
Logical, insulating liquid is filled with by pipeline road 4 to wavy metal expanding core body 5.
The working principle of the utility model are as follows:
Under original state, exhaust pipe 2 is normally open, and relief tube 1 is normally off.Wavy metal expansion in cabinet body 6
Core 5 carries out oiling by pipeline road 4.When wavy metal expanding core body 5 runs to the extreme position of setting, binary channels row
The valve head of journey valve 3 touches the cabinet cover limit plate on 6 inner wall of cabinet body, opens binary channels stroke valve 3, and exhaust pipe 2 is closed, relief tube
1 is opened, and carries out pressure release, draining.
