Description
Technical field
The present invention relates to high-tension switch cabinet field more particularly to a kind of pressure release cooling device, specially a kind of high-voltage switch gears
The releasing pressure automatically cooling device of cabinet.
Background technique
High-tension switch cabinet refers to for playing on-off, control in electric system power generation, transmission of electricity, distribution, electric energy conversion and consumption
Or the effects of protection, switchgear has the function of aerial inlet-outlet line, cable incoming-outgoing wire, bus contact etc..Be primarily adapted for use in power plant,
The various different places such as substation, petrochemical industry, metallurgical steel rolling, industry light industry textile industry, industrial enterprise and residential quarters, skyscraper.
In the process of running, (such as short circuit, insulation ag(e)ing, human operational error) makes high-tension switch cabinet because of various reasons
Occur at primary circuit short trouble, under tens of thousands of amperes of short circuit current, moment generates high temperature and high pressure gas, if high temperature and pressure
Gas cannot effectively discharge in a very short period of time in narrow cabinet body, will cause switchgear and burst, the damage of adjacent switch cabinet,
Life safety may be injured simultaneously.Therefore, effective pressure-relief measure must be taken into consideration when switchgear designs.
The existing common pressure relief device of high-tension switch cabinet is mainly made of pressure release metal plate and nylon bolt, works as switchgear
Interior high temperature air pressure gradually rises, and pressure release metal plate is automatically opened after melting nylon bolt, to accomplish that vented gasses release stress.
After melting nylon bolt, the high pressure gas in cabinet easily goes out pressure release metal plate, is easy to hurt staff,
Security risk is caused, while the lower pressure relief device can not cool down to the gas of temperature and discharge in cabinet, not can guarantee out
The equipment closed in cabinet is in suitable operating temperature, meanwhile, the staff that may burn is discharged in the gas of high temperature, and influences
The working environment of operator.
In the Chinese patent application No. is CN201721703109.7, proposes to carry out pressure release using piston apparatus, work as work
Plug sounds an alarm when touching sensor, prompts staff to open manual bolt manually and carries out pressure release to gas in cabinet body, works as nothing
When staff is on the scene, pressure, which reaches spheric granules after certain value and is ejected, reaches emergency decompression.In the technical method, when no work
Make that personnel are on the scene to be, air pressure, which will reach certain value, just can be carried out releasing pressure automatically, may be to switch during air pressure is raised
Device in cabinet causes to damage, if after air pressure increases to certain value, staff just has found and carries out manual pressure release, it is likely that by
It is excessive in air pressure in device and staff is damaged in pressure release.
