Abstract
The utility model relates to a decompression explosion-proof device of a high-pressure switch cabinet, comprising a closed-type switch cabinet, a hinge, a metal explosion-proof top plate and a nylon screw. The decompression explosion-proof device of the high-pressure switch cabinet is characterized in that the closed-type switch cabinet is connected with two metal explosion-proof top plates through the hinge; and the upper and lower ends at the inner side of the metal explosion-proof top plate are fixedly connected with a top sealing plate through the nylon screw. The utility model has the technical effect that the malignant accident that the operators are seriously burnt caused by unsmooth release of fault gas pressure of the closed-type switch cabinet and release of high-temperature airflow from the front side of the high-pressure cabinet can be effectively prevented by improving the pressure releasing device of the closed-type switch cabinet. The utility model improves the decompression explosion-proof performance, is convenient to complete release of explosive gas, has safe and reliable operation and ensures the reliability of operation of the pressure releasing device.
Description
Technical field
The utility model relates to a kind of explosion-protection equipment, relates in particular to a kind of high-tension switch cabinet decompression anti-explosion device.
Background technology
The accident of closed high-tension switch cabinet safety relief passage, there is defective in the safety relief passage that betides switch cubicle mostly, and safe pressure relief device is not smooth, and high temperature gas flow discharges by high-voltage board is positive, causes operating personnel's serious burn.It freely is not the major reason that causes the accident and enlarge that enclosed switchgear failure gas pressure discharges.
In design to closed high-tension switch cabinet, the problem that high-temperature gas pressure discharges when generally structurally all having considered fault.In the circuit breaker cart chamber, the top of bus-bar room and cable vault is equipped with pressure relief device, is a rectangle metal top plate, and a side is fixed with iron screw, and opposite side is fixed with nylon screw.When circuit breaker or bus-bar room generation internal fault electric arc, follow the appearance of electric arc, the switch cubicle air pressure inside raises, the special seal circle that is installed on the door is closed the cabinet front, the pressure release metal top plate of top equipment will be out of shape and be opened automatically, release pressure and drainage gas are to guarantee the safety of operating personnel and switch cubicle.Top board is scrapped after the pressure release.
In actual motion, bus-bar room rectangle metal top plate requires bigger because volume is bigger to fault high-temperature gas pressure, when fault pressure hour can not in time be got rid of, easily cause overstocking of fault pressure, be difficult to satisfy the release fully than glitch pressure, security performance can not embody fully.
Summary of the invention
The purpose of this utility model is to provide a kind of high-tension switch cabinet decompression anti-explosion device, by the enclosed switchgear pressure relief device is implemented to improve, can effectively prevent because enclosed switchgear failure gas pressure discharges not smooth, high temperature gas flow discharges by high-voltage board is positive, causes the serious accident of operating personnel's serious burn.
The utility model is achieved like this, it comprises enclosed switchgear, hinge, the explosion-proof top board of metal, nylon screw, it is characterized in that the enclosed switchgear two explosion-proof top boards of metal that are connected through the hinge, the inboard upper and lower side of the explosion-proof top board of metal is fixedlyed connected with top sealing plate by nylon screw.
Technique effect of the present utility model is: by the enclosed switchgear pressure relief device is implemented to improve, can effectively prevent because enclosed switchgear failure gas pressure discharges not smooth, high temperature gas flow discharges by high-voltage board is positive, causes the serious accident of operating personnel's serious burn; Improved the pressure-relief explosion-proof performance, be convenient to explosion gas and discharge fully, handling safety is reliable, has guaranteed the reliability of pressure relief device action.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Enclosed switchgear 2, hinge 3, the explosion-proof top board 4 of metal, nylon screw in the drawings, 1,
Embodiment
As shown in Figure 1, the utility model is achieved like this, enclosed switchgear 1 connects two explosion-proof top boards 3 of metal by hinge 2, and the inboard upper and lower side of the explosion-proof top board 3 of metal is fixedlyed connected with top sealing plate by nylon screw 4.When bus-bar room generation internal fault electric arc, follow the appearance of electric arc, enclosed switchgear 1 air pressure inside raises, the special seal circle that is installed on the door is closed the cabinet front, explosion-proof 3 top boards of pressure release metal of top equipment are opened to both sides fully with the deformation image door is the same, release pressure and drainage gas are to guarantee the safety of operating personnel and switch cubicle.
