Abstract
The utility model relates to a pressure releasing device. The pressure releasing device comprises pressure releasing channels, the pressure releasing channels which are communicated with units in a switch cabinet extend to the top of the switch cabinet, a top cover plate is a movable cover plate, an opening and closing end of the top cover plate is fixed to the switch cabinet through a top cover nylon screw, the top cover plate is provided with top cover shutters, and the top cover plate is a hinge type movable cover plate. The pressure releasing device provided by the utility model can solve the problem of difficult pressure release of a high-voltage switch cabinet, and can effectively guide a jet direction of an electric arc, releasing energy of high pressure gas, and ensuring safety of operators on duty; and the whole device is simple to machine, convenient and rapid to mount, is suitable for factory construction, and facilitates transforming of an existing switch cabinet in operation in a transformer substation. The pressure releasing device goes through internal arcing test detection of a plurality of national authoritative test stations, and can fully achieve requirements on an internal arcing failure in national standards.
Description
Technical field
The utility model relates to a kind of safety device, in particular for the pressure relief device of each functional unit in the high-tension switch cabinet.
Background technology
The mode that domestic existing 3～40.5kV high-tension switch cabinet adopts pressure to discharge mainly is by pressure release passage or pressure relief plate, the pressure release passage of the high-tension switch cabinet of employing pressure release passage is often fastening by iron screw, even it is by the mode of electric welding that the lamina tecti weldering is dead, fault pressure dashes not open, and does not have the pressure release effect; Do not offer shutter on the pressure relief plate of the high-tension switch cabinet of employing pressure relief plate, whole switch cubicle does not have air duct, the heat radiation of having no idea; Even some high-tension switch cabinet is not established pressure release passage.In a single day internal fault takes place in above-mentioned high-tension switch cabinet, and inner elevated pressure rapidly can not get discharging, and very easily accident is enlarged, even causes human casualty accident, leads to serious consequence.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of pressure relief device, and the pressure that can solve high-tension switch cabinet discharges difficult problem, and the pilot arc direction of spraying effectively discharges the energy of gases at high pressure, guarantees operator on duty's safety.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of pressure relief device, comprise pressure relief channels,
The pressure relief channels that is connected with each unit in the switch cubicle extends to the switch cubicle top, and lamina tecti is removable cover, and the folding end of lamina tecti is fixed on the switch cubicle by the top cover nylon screw, offers the top cover shutter on the lamina tecti.
Lamina tecti is the hinge type removable cover.
Lamina tecti one end is fixed on the switch cubicle by the top cover loose-leaf.
Lamina tecti is that thickness is the cold-rolled steel sheet of 1.5mm.
The thread neck part diameter of top cover nylon screw is 5mm.
Pressure relief channels is made up of main bus bar chamber pressure release passage and breaker chamber pressure release passage.
Lamina tecti is made up of top blind flange and breaker chamber lamina tecti.
The pressure relief device that the utility model provides, beneficial effect is as follows:
1, to work as gases at high pressure when breaking down and electric arc by the pressure relief channels that extends to switch cubicle top delivers to cabinet and pushes up, the design of top cover shutter and shutter makes whole switch cubicle form effective circulation heat dissipation channel, discharge a part by the top cover shutter, when pressure continues to increase, can thrust by the top cover nylon screw that intensity is not high, open movable lamina tecti, abundant release pressure and electric arc, simultaneously because lamina tecti is the hinge type removable cover, lamina tecti can not be dashed flies to injure the person, and very little pressure just can be opened pressure relief device, and the direction of pressure release simultaneously is ceiling, can not produce harm to the people, avoid accident expansion.
2, the pressure that can solve high-tension switch cabinet discharges difficult problem, and the pilot arc direction of spraying effectively discharges the energy of gases at high pressure, guarantees operator on duty's safety.
3, whole device processing is simple, and it is convenient to install, and both has been fit to factory's construction, makes things convenient for transformer station that the switch cubicle of existing operation is transformed again.Inside arcing test by a plurality of national authorities experiment station detects, and to the requirement of inner arcing fault, is subjected to users' such as the approval of the department of detecting and power supply administration favorable comment in can being up to state standards fully.
4, lamina tecti is preferably the cold-rolled steel sheet that thickness is 1.5mm, has both guaranteed the degree of protection of switch cubicle, alleviates cover plate weight again, and cover plate is opened easily.
5, the top cover nylon screw is preferably the nylon screw that the thread neck part diameter is 5mm, makes that screw is easier to be thrust.

Embodiment
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 and shown in Figure 6, the utility model comprises pressure relief channels, the pressure relief channels 4 that is connected with each unit in the switch cubicle extends to the switch cubicle top, lamina tecti 1 is removable cover, the folding end of lamina tecti 1 is fixed on the switch cubicle by top cover nylon screw 2, offers top cover shutter 3 on the lamina tecti 1.
Lamina tecti 1 is the hinge type removable cover.
Lamina tecti 1 one ends are fixed on the switch cubicle by top cover loose-leaf 5.
Lamina tecti 1 is the cold-rolled steel sheet of 1.5mm for thickness.
Pressure relief channels is made up of main bus bar chamber pressure release passage 6 and breaker chamber pressure release passage 7.
Lamina tecti 1 is made up of top blind flange 8 and breaker chamber lamina tecti 4.
Assembling process of the present utility model is as follows:
When the assembling switch cubicle, earlier pressure relief channels, lamina tecti 1 are assembled, the more whole assembling that links to each other with switch cubicle.Lamina tecti 1 is fixed on the switch cubicle top by fixed lamina tecti 9.
