Background technology
Transformer is a kind of important transmission of electricity transformer equipment, and inside transformer current density is big in the process of running,
Temperature is high, often because short circuit causes flashover after long-play in the environment of high pollution and high humility, in order to anti-
Only electric current flashover impacts other electric power components in transformer, and designer often fills into the transformer tank body of sealing
Fluid injection state insulating oil achievees the purpose that cooling and anti-flashover, but in the actual use process, when flashover occurs with this
When, impact caused by electric current explodes can spray insulating oil from transformer oil inlet, be polluted to other electric power components.
Utility model content
The technical assignment of the utility model is to solve the deficiencies in the prior art, provides a kind of anti-quick-fried gas bleeder valve of sudden strain of a muscle of transformer.
The core concept of the design is：Design it is a kind of have suppression oil and oil return function anti-flashover gas bleeder valve, inside set
Two-stage exhaust gear i.e. the first guiding valve and the second guiding valve are counted, when flashover occurs in transformer, high pressure draught carries fluid oil
Second guiding valve is jacked up, the second guiding valve drives piston stroking upward, high pressure draught to be let out by first on the first guiding valve and the second guiding valve
Stomata and the second bleeder port enter in the first air guide column and the second air guide column, are released using the first muffler and the second muffler
It is put into the external world, in the process, the hydraulic oil that high pressure draught is carried from transformer-cabinet can be adhered to slide-valve surface and gather
In fuel reserve tank, flowed back into transformer eventually by the bleeder port on the first guiding valve.
The utility model is scheme used by solving technical problem：
A kind of transformer is anti-to dodge quick-fried gas bleeder valve, including the first guiding valve and the second guiding valve, the installation that the first guiding valve passes through bottom
Flange is mounted on the bottom of oil storage tank, and the second guiding valve is mounted in the first guiding valve, and stop flange arranged at the bottom of the second guiding valve, and first
There are the first bleeder port, the first bleeder port to be located at the bottom of the first guiding valve side wall, have on the side wall of the second guiding valve on the side wall of guiding valve
Second bleeder port, the second bleeder port are located at the middle part of the second guiding valve side wall, have piston card slot, piston card slot at the top of the second guiding valve
Interior installation piston.
The bottom of oil storage tank has air intake duct, top to have block, block to be bolted with oil storage tank, the middle part of oil storage tank
There are the first air guide column and the second air guide column, has the first muffler and the second noise reduction at the top of the first air guide column and the second air guide column
Device.
The diameter of piston is equal to the internal diameter of oil storage tank, and sealing ring is installed on piston, there is spring, spring and lid at the top of piston
Cap is connected.
A kind of transformer of the utility model is anti-to dodge quick-fried gas bleeder valve, and the prior art is compared to generated advantageous effect：
1) when dodging outburst life inside transformer-cabinet, the insulating oil that high pressure draught is swept along touches guiding valve and in cunning first
The condensed on inner walls of valve flows back, and has thus filtered most insulating oil.
2) high pressure draught jacks up the second guiding valve, and the second guiding valve drives piston stroking upward by the first air guide column and the second air guide column
Valve open, air-flow escaped by the first muffler and the second muffler in external environment, remaining insulating oil in air-flow
Slide-valve surface can be adhered to and accumulated in fuel reserve tank, flowed back into transformer eventually by the bleeder port on the first guiding valve.
3) after the completion of exhaust, piston can automatically restore to initial position under the action of the spring, thereby realize
The closing of slide valve system avoids the insulating oil that external dust enters in transformer to inside transformer and pollutes.

Specific implementation mode
The embodiments of the present invention are illustrated in conjunction with attached drawing.
A kind of transformer is anti-to dodge quick-fried gas bleeder valve, including the first guiding valve 2 and the second guiding valve 3, the peace that the first guiding valve 2 passes through bottom
The bottom that flange is mounted on oil storage tank 1 is filled, the second guiding valve 3 is mounted in the first guiding valve 2, and limit method is arranged at the bottom of the second guiding valve 3
Orchid has the first bleeder port 4, the first bleeder port 4 to be located at the bottom of 2 side wall of the first guiding valve, the second guiding valve on the side wall of the first guiding valve 2
