Description
Technical field
The present invention relates to power distribution cabinet safeguard construction technical fields, more particularly to withdraw-type AC metal closed switch cabinet.
Background technology
The small high voltage switch cubicle of a part is semi-hermetic type high-tension switch cabinet at present, and certain ventilation and heat is as arranged
Position, however, to ensure that not interfered by extraneous factor, the aperture of the ventilating heat dissipating hole or shutter is all compared
It is small.When high-tension switch cabinet causes one due to short circuit, insulation ag(e)ing or human operational error etc. in the process of running
When minor loop short trouble occurs, under tens thousand of amperes of short circuit current, the high temperature and high pressure gas that moment generates is in narrow cabinet
It cannot be released effectively within the extremely short time in vivo, it is possible to high-tension switch cabinet can be caused to burst, lead to adjacent high-tension switch cabinet
Damage, while personal safety may be injured.Therefore high-tension switch cabinet must have effective pressure-relief measure.Prior art mesohigh
The pressure-relief measure that switchgear is taken mainly by top pressure release, i.e., opens up relief hole at top.Also have using fiberglass or Asia
The pressure relief plate of material is made every effort to overcome, but the former is easy to cause in high pressure vacuum high-tension switch cabinet and falls into dust, the latter is in high temperature and pressure
It is rushed to open under the effect of gas crunch, can fly in switchgear house civil strike, be easy to injure or smash miscellaneous equipment by a crashing object, or even to watch
Member damages.
Invention content
The present invention improves the safety of withdraw-type AC metal closed switch cabinet by setting novel pressure relief valve, into
One step improves the service life of withdraw-type AC metal closed switch cabinet.
In order to solve the above technical problems, the present invention provides a kind of withdraw-type AC metal closed switch cabinet, including cabinet,
