Abstract
The utility model discloses an explosion-proof device in particular to an explosion-proof elbow for a transformer, comprising a elbow, joint flanges arranged at both ends of the elbow and a flange connected with a gland by a bolt. The utility model is characterized in that a sealing washer, a explosion-proof valve flake and a glass plate are orderly arranged between the flange and the gland; the joint flanges are connected with lower terminal of the transformer; direction of the flange used as a pressure discharge opening is downward; the explosion-proof valve flake takes a shape of disc and is made from aluminum alloy or copper alloy; circular-ring shaped grooves are arranged on both lateral face of the explosion-proof valve flake according to need of rating explosion-proof pressure. The utility model is a safety device for preventing damage to human and equipment caused by inner failure of the transformer. The utility model has an advantage of secondary security protection. The utility model is mainly used in safety protection for 35 kV grade and lager transformer.
Description
(1) technical field
The utility model relates to a kind of explosion-protection equipment, is specially the explosion-proof bend pipe of a kind of transformer.
(2) background technology
Present stage, the transformer phenomenons such as internal fault such as flashover, creepage, short circuit that are in operation happen occasionally, and easily cause increasing rapidly of transformer-cabinet internal pressure.For the rapid expansion that anti-phenomenon here causes the accident, adopt the rapid pressure release of pressure relief valve usually.The motion of pressure relief valve depended on pressure spring and valve block discharges transformer oil pressure, factors such as clamping stagnation, action is malfunctioning, the force value adjustment is inaccurate takes place have the rapid expansion that easily causes the accident often; Simultaneously pressure relief valve is installed in the top of transformer, and as people during near transformer equipment, the unexpected oil spout meeting of pressure relief valve constitutes a threat to personal safety.
(3) summary of the invention
The utility model is in order to remedy the deficiencies in the prior art, provides a kind of and is active in one's movements, the explosion-proof bend pipe of transformer of handling safety.
The technical solution of the utility model is:
The explosion-proof bend pipe of a kind of transformer, the coupling flange, the flange that comprise bend pipe and lay respectively at its two ends, flange is connected with gland by bolt, its special character is: seal washer, explosion-proof valve block, sheet glass are installed between described flange and the gland successively, coupling flange is connected in the lower end of transformer, is directed downwards as the flange of pressure release orifice.
The explosion-proof bend pipe of transformer of the present utility model, explosion-proof valve block is disc-shape, and its material is aluminium alloy or copper alloy, and explosion-proof valve block two sides have annular groove according to specified explosion-proof pressure needs.
The utility model be a kind of for the prevention transformer because of the internal fault factor jeopardizes the person and the safeties of device security, played secondary security protection effect.This design is mainly used in the safeguard protection of 35kV level and above transformer.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 looks schematic diagram for master of the present utility model;
Fig. 2 looks schematic diagram for the right side of the present utility model;
Fig. 3 is a schematic top plan view of the present utility model;
Fig. 4 is the scheme of installation of the utility model on transformer;
Fig. 5 is the structural representation of explosion-proof valve block in the utility model;
Fig. 6 is the generalized section of explosion-proof valve block in the utility model.
Among the figure: 1 is coupling flange; 2 is bend pipe, and 3 is flange, and 4 is seal washer; 5 is explosion-proof valve block, 6 sheet glass, and 7 glands, 8 bolts, 9 is the explosion-proof bend pipe of transformer; 10 is transformer; 11 is stone.
(5) embodiment
Fig. 1 to Fig. 3 is a kind of specific embodiment of the present utility model.The explosion-proof bend pipe of the transformer of this embodiment comprises bend pipe 2 and lays respectively at the coupling flange 1 at its two ends, flange 3 that flange 3 is connected with gland 7 by bolt 8, and seal washer 4, explosion-proof valve block 5, sheet glass 6 are installed between flange 3 and the gland 7 successively.As Fig. 5, shown in Figure 6, explosion-proof valve block 5 is disc-shape, and its material is aluminium alloy or copper alloy, and explosion-proof valve block 5 two sides have annular groove according to specified explosion-proof pressure needs.H is that thickness is torn in the design of explosion-proof valve block, and its size is determined according to material shearing stress and specified explosion-proof pressure.
As shown in Figure 4, when normally using the explosion-proof bend pipe 9 of transformer, make coupling flange 1 be connected in the lower end of transformer 10, connect mutually by bolt with the fuel tank of transformer 10, transformer oil pressure release direction is downward, and promptly the flange 3 as pressure release orifice is directed downwards.When transformer normally moved, explosion-proof valve block 5 bore transformer oil pressure, prevents the transformer oil seepage by seal washer 4, and sheet glass 6 is used to protect explosion-proof valve block 5, anti-air oxidation.Because internal fault when causing transformer oil pressure to rise rapidly, if the transformer oil insufficient pressure is during with the explosion-proof valve block 5 in the explosion-proof bend pipe of bursting, this pressure is by the pressure relief valve releases that is installed on the transformer when transformer; If move when malfunctioning because of internal fault causes the excessive or pressure relief valve of transformer oil pressure, transformer oil pressure is applied on the explosion-proof valve block 5 in the explosion-proof bend pipe when enough big, make explosion-proof valve block 5 tear and spray from the ring-shaped groove thinnest part, transformer oil is discharged in the filling stone 11 in the melt pit, can prevent that oil spout from hurting sb.'s feelings or cause fire, the explosion-proof bend pipe of transformer has played secondary security protection effect.
Claims (2)
1. explosion-proof bend pipe of transformer, the coupling flange (1), the flange (3) that comprise bend pipe (2) and lay respectively at its two ends, flange (3) is connected with gland (7) by bolt (8), it is characterized in that: seal washer (4), explosion-proof valve block (5), sheet glass (6) are installed between described flange (3) and the gland (7) successively, coupling flange (1) is connected in the lower end of transformer (10), is directed downwards as the flange (3) of pressure release orifice.
2. the explosion-proof bend pipe of transformer according to claim 1 is characterized in that: explosion-proof valve block (5) is disc-shape, and its material is aluminium alloy or copper alloy, and explosion-proof valve block (5) two sides have annular groove according to specified explosion-proof pressure needs.
