Abstract
The utility model discloses an explosion-proof device of a high-voltage switch cabinet. The explosion-proof device comprises an upper holder and a lower holder, the upper holder and the lower holder are fixedly mounted on an air chamber of the high-voltage switch cabinet, the upper holder is fixedly connected with the lower holder, and a counter-arc rupture disc is arranged between the upper holder and the lower holder. When pressure in the air chamber is over the bearing pressure of the rupture disc, the rupture disc is damaged, and pressure is released effectively, thereby guaranteeing safety of the switch cabinet body and all the elements in the switch cabinet body by replacing damaged rupture disc only. The explosion-proof device is safe, reliable, convenient and practical and reduces operation cost.
Description
Technical field
The utility model relates to a kind of high-tension switch cabinet explosion-protection equipment, particularly a kind of high-tension switch cabinet explosion-protection equipment that can be convenient for changing.
Background technology
Be provided with explosion-protection equipment owing to having gases at high pressure in the air chamber of high-tension switch cabinet, in order to various components and parts in the protection cabinet.At present, the extensive explosion-protection equipment that adopts by welded and installed at high-voltage switch gear cashier's office in a shop, and is integrated with cabinet, and like this, because hypertonia is exploded, though protected other components and parts, cabinet also can be owing to the damage of explosion-protection equipment is scrapped when explosion-protection equipment; Another kind is that demolition set is integrated, in case damage, whole demolition set needs to change, and causes greatly inconvenience, the operating cost height.
The utility model content
In order to solve the above problems, the purpose of this utility model is to provide a kind of can conveniently be installed to high-voltage switch gear explosion-protection equipment cashier's office in a shop, and it is simple in structure, and can change at any time, and is safe and reliable.
The technical scheme that the invention for solving the technical problem adopted is:
A kind of high-tension switch cabinet explosion-protection equipment comprises the last clamper, the lower gripper that are fixedly mounted on the high-tension switch cabinet air chamber, and the described clamper of going up is fixedlyed connected with lower gripper, and described going up between clamper and the lower gripper is provided with the antiarch rupture disk.
As the further improvement of above-mentioned execution mode, described upward clamper and lower gripper and high-tension switch cabinet air chamber are installed to connect the groove that the face that touches is provided with the installation sealing ring are installed.
As the further improvement of above-mentioned execution mode, described upward clamper and lower gripper are connected and fixed by argon arc welding.
The beneficial effects of the utility model are: because the antiarch rupture disk is installed between the upper and lower holder, after the pressure in the air chamber surpasses the bearing pressure of rupture disk, rupture disk destroys, pressure release effectively, thereby guarantee the safety of each element in switch cabinet body and the cabinet, and the rupture disk that only need change damage gets final product, safe and reliable, convenient and practical, and reduced operation costs.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model schematic top plan view.
Embodiment
With reference to Fig. 1, Fig. 2, a kind of high-tension switch cabinet explosion-protection equipment, comprise the last clamper 1, the lower gripper 3 that are fixedly mounted on the high-tension switch cabinet air chamber, the described clamper 1 of going up is fixedlyed connected with lower gripper 3, described going up between clamper 1 and the lower gripper 3 is provided with antiarch rupture disk 2, antiarch rupture disk 2 is clamped between the upper and lower holder 1,3.When the rupture disk pressure-bearing simultaneously be subjected to after pressure surpasses its bearing pressure, rupture disk breaks, thus the switch cubicle pressure release, the safety of all kinds of components and parts in the protection switch cabinet, and need can come into operation once more by changing rupture disk, convenient and swift, practical economical.
In order to guarantee upper and lower holder 1,3 and cabinet installation position sealing, the described clamper 1 of going up is provided with the groove 11,31 that sealing ring is installed with lower gripper 3 and high-tension switch cabinet air chamber installation contact-making surface.
As optimal way, described clamper 1 and the lower gripper 3 gone up is connected and fixed by argon arc welding.
Certainly, the invention is not limited to above-mentioned execution mode, as long as it reaches technique effect of the present utility model with essentially identical means, all should belong to protection range of the present utility model.
