Description
Technical field
The utility model relates to a kind of high-tension switch cabinet, in particular to a kind of select mining high voltage switch cabinet.
Background technique
High-tension switch cabinet be it is a kind of generated electricity in electric system, transmitted electricity, the conversion of distribution and electric energy during, opened
Close, control and protect electrical equipment.Component in switchgear mainly have breaker, disconnecting switch, on-load switch, operating mechanism,
The composition such as mutual inductor and various protective devices.Dressing plant is generally required more corresponding height of outfit and is pressed off as needed for production
Close cabinet.It, may be because of originals such as short circuit, insulation ag(e)ing or human operational errors due in the operational process of high-tension switch cabinet
Cause will cause circuit short circuit, the high temperature and high pressure gas for causing short circuit current moment to generate.In dressing plant, in order to prevent dust into
Enter in high-tension switch cabinet body, the leakproofness between high-tension switch cabinet ontology and cabinet door is natively arranged relatively good.In addition cabinet door
And switch cabinet body is at high temperature, if a small amount of expansion can be generated, will lead to closed between high-voltage switch gear cabinet body and cabinet door
Type is more preferable.In this way, high temperature and pressure will steeply rise nowhere in the state of pressure release, if cannot in a very short period of time,
Pressure is discharged from cabinet body, it is possible to will lead to switchgear and burst, cause to jeopardize personal peace while damaging adjacent switch cabinet
Entirely.
To solve the above problems, traditional high-tension switch cabinet mainly passes through top pressure release, i.e., relief hole is opened up at top.
Dressing plant's dust is more, and this structure, which is easy to cause in high-tension switch cabinet, falls into dust.The entrance of dust is likely to result in circuit fortune
The unstable generation with security risk of row.So many producers all use not the pressure relief mechanism for influencing circuit operation at present, most
Common two kinds are: 1) use rupture disk, when high-tension switch cabinet internal pressure greatly to a certain degree when, under high pressure, rupture disk
It is directly broken to carry out pressure release.Although solving the problems, such as that dust enters, needs to add protection mechanism, rupture disk is prevented to hurt
People.And the selection of rupture disk, sealing, location and installation etc., technical problem is larger, both improves cost, and be easy to appear high pressure not
Can be by designing rupture disk explosion the problem of.2) elastic material is used, equally there are material selection, the skills such as sealing, location and installation
Art problem.And be most importantly, when high pressure struts elastic material, illustrate it is high pressure conditions in cabinet body, that is to say, that only
It is high pressure conditions in cabinet body, elastic material can be just softened.Which results in be always to be in high temperature inside high-tension switch cabinet
Under high pressure conditions, equally there is security risk.
Therefore, design is a effectively can quickly carry out pressure release, not influence normal operation circuit, and simple structure, installation
Convenient, low in cost, the mining high voltage switch cabinet that selects there is no security risk is the research purpose of the utility model.
Utility model content
For above-mentioned technical problem of the existing technology, the utility model lies in that providing a kind of ore dressing high-voltage switch gear
Cabinet, this selects mining high voltage switch cabinet to can effectively solve the problem that above-mentioned technical problem of the existing technology.
The technical solution of the utility model is:
It is a kind of to select mining high voltage switch cabinet, including switch cabinet body, pressure relief mechanism, alarm mechanism and control system, it is described
The front side of switch cabinet body is equipped with corresponding cabinet door, and the rear side of switch cabinet body is connected with corresponding relief tube, institute
Stating pressure relief mechanism includes rubber pneumatic bag, is connected with a corresponding communicating pipe by adhesive means at the gas nozzle of the rubber pneumatic bag,
The communicating pipe is sealably coupled to the relief tube using thread connecting mode, and communicating pipe is equipped with corresponding solenoid valve, institute
Stating rubber pneumatic bag is evacuated state；Device has corresponding pressure gauge, the pressure gauge and the electricity in the switch cabinet body
Magnet valve is connected respectively to the control system.
The alarm mechanism includes buzzer siren and LED warning lamp, and the buzzer siren and LED warning lamp connect respectively
It is connected to the control system.
The bottom rear of the switch cabinet body is connected with a corresponding support plate, and the support plate is equipped with and is used to support
The cambered surface locating slot of the rubber pneumatic bag.
The advantages of the utility model:
When the utility model is assembled, by corresponding equipment then rubber pneumatic bag is closed solenoid valve into vacuumizing
It closes, and will be directly connected on relief tube communicating pipe.When pressure gauge senses that the pressure inside switch cabinet body is up to one
When definite value, electric signal is sent to control system by pressure gauge, and control system control buzzer siren and LED warning lamp issue respectively
Alarm, remind relevant staff come the row of progress danger handle.At the same time, control system control solenoid valve is opened, and makes pressure release
Pipe and communicating pipe, the rubber pneumatic bag under evacuated state restored rapidly shape at connected state, generates certain suction pressure effect, opens
The pressure for closing cabinet body interior is let out in rubber pneumatic bag rapidly.Related personnel can directly open cabinet door and carry out related danger after rushing to
Feelings processing and investigation.It realizes and effectively quickly carries out pressure release, do not influence normal operation circuit, and simple structure, install convenient, cost
It is cheap, be not present security risk the advantages of.
