Description
Technical Field
The utility model belongs to the technical field of the middling pressure cabinet, in particular to cubical switchboard pressure release structure.
Background
The medium-voltage switch cabinet requires that each high-voltage compartment is provided with a respective pressure relief channel, so that pressure, heat and the like are quickly released when an internal arc fault occurs, equipment and personal safety are ensured, and the pressure relief is realized in a mode that a pressure relief plate is installed on the top of the cabinet. The existing installation mode of the pressure relief plate at the top of the medium-voltage switch cabinet has the defects of heavy weight, slow pressure relief and heat dissipation, insecure fixation, easy flying-out of the pressure relief plate, complex design, high cost and the like.
Disclosure of Invention
In order to solve the problem, the utility model provides a novel pressure release structure, one side through the fixed pressure release board of easy cracked nylon bolt is through the opposite side of the fixed pressure release board of high strength bolt for the pressure release board can be washed away by oneself under high temperature high pressure state.
In order to realize the above purpose, the utility model provides a cubical switchboard pressure release structure, including pressure release board, pressure release mouth, the pressure release mouth is located the cabinet body of cubical switchboard, the pressure release board sets up in the top of pressure release mouth and covers the pressure release mouth, nylon bolt fastening is passed through on the cubical switchboard cabinet body in one side of pressure release board, the one side relative with nylon bolt on the pressure release board is passed through high strength bolt fastening on the cubical switchboard cabinet body.
Furthermore, the structure further comprises a pressure relief plate pressing strip, wherein the pressure relief plate pressing strip is located between the high-strength bolt and the pressure relief plate, and the high-strength bolt penetrates through the pressure relief plate pressing strip and fixes one side of the pressure relief plate on the switch cabinet body.
Further, the high-strength bolt is an iron bolt.
Furthermore, the pressure relief plate is fully punched with dense round holes, and the diameter of the round holes is smaller than 1 mm.
Furthermore, the pressure relief plate is a galvanized steel plate with the thickness of 0.5-2 mm.
Further, the thickness of the pressure relief plate pressing strip is larger than 2 mm.
Further, the pressure relief plate has a protection rating of IP 4X.
Furthermore, the number of the nylon bolts is 2.
The utility model has the advantages as follows:
1. through the fixed one side of holding down plate of easy fracture nylon bolt, when cubical switchboard internal pressure and heat sharply rise, the nylon bolt fracture releases the cabinet internal pressure, guarantees safety.
2. Through set up the pressure relief board layering between high strength bolt and pressure relief board, guarantee the fixed strength of high strength bolt side pressure relief board, prevent that the pressure relief board fracture from causing the incident.
3. The round hole is formed in the pressure relief plate, so that the pressure relief and heat dissipation of the switch cabinet are facilitated, and the safety of the interior of the cabinet body is guaranteed.
