Description
Technical field
The invention belongs to electrical equipment technical field, particularly a kind of sealed explosion-proof distribution box.
Background technology
Distribution box is that switchgear, measuring instrumentss, protection electrical equipment and auxiliary equipment are assembled in into envelope by electrical wiring requirement
Close or semiclosed metal safe in or screen width on, form low-tension distribution box；It can be connected during normal operation by manual or automatic switch
Or disjunction circuit；By protection electrical equipment cut-out circuit or alarm when failure or irregular operating；Operation can be shown by means of measuring instrumentss
In various parameters, some electric parameters can be also adjusted, to deviate normal operating conditions prompted or sent signal.
Distribution box can reasonably distribute electric energy, the convenient switching action to circuit, have higher class of safety protection, can intuitively show
Show the conducting state of circuit.
Explosion-proof electrical distribution box often uses in the Workplace for be mixed with explosive gas, and explosion-proof electrical distribution box is worked
Electric spark will be inevitably produced in journey, once explosive gas connects in the electric spark and Workplace in explosion-proof electrical distribution box
Touch, it will trigger blast, cause serious production accident, bring huge economic loss and casualties.
Explosion-proof electrical distribution box typically completely cuts off the inside and outside connection of distribution box by sealing structure, prevents thing of exploding
Therefore and existing explosion-proof electrical distribution box can not be safeguarded timely typically all without the device for detecting sealing in real time.
Existing explosion-proof electrical distribution box is normally only provided with warning mark, can be straight when needing to operate in distribution box or repairing
Unlatching distribution box is connect, and circuit is also can turn on when casing is opened, this causes the fiery gas cognition of outside directly and distribution
Case contacts, and explosion accident occurs, therefore security is very low.
The content of the invention
The present invention is in view of the shortcomings of the prior art, provide a kind of sealed explosion-proof distribution box, this kind of distribution box can be to distribution box
Sealing detected in real time, effectively prevent the door of distribution box from arbitrarily opening, it is necessary to distribution box power-off after could open,
And it can just be continuously turned on circuit on the premise of casing closes guarantee sealing.
In order to solve the above-mentioned technical problem, the present invention is addressed by following technical proposals：A kind of sealed explosion-proof distribution
Case, including casing, be provided with door on the casing, be provided with sealing strip on the door, on the casing in be provided with air pump, it is described
Air pump is connected with compressed gas cylinder, and the air pump is realized switching manipulation by the magnetic force knob outside the casing, set in the casing
The toggle switch for distribution control box way circuit is equipped with, the toggle switch is provided with driving lever, gas is provided with the casing
Cylinder, the cylinder is interior to be provided with push rod and chute, and the chute is interior to be provided with waist hole, the driving lever filled with gas, the push rod
On be provided with gag lever post, the gag lever post slides in the waist hole.During this kind of explosion-proof electrical distribution box door opening state, the push rod of cylinder
In retracted mode, now toggle switch is closed, and when distribution box needs to open, chamber door is closed, passes through magnetic force knob control
Gas in casing is pumped into compressed gas cylinder by air pump processed so that the gas in casing thins out, and casing is not susceptible to fire
Burn；Air pressure diminishes during gas is extracted out, and the push rod auto-extending of cylinder opens toggle switch, in this condition, matches somebody with somebody
The door of electronic box is because draught head is held out against, unlatching that door can not be random, while under the state, if there is the situation cylinder of gas leakage
Push rod retract automatically distribution box way circuit closed the driving lever of toggle switch to automatically, ensure security；When to open,
Control air pump that gas in compressed gas cylinder is put back into casing by magnetic force knob, now the push rod of cylinder will be retracted automatically to stir
The driving lever of switch closes distribution box way circuit automatically, and door can also be opened, so as to ensure when casing is opened nothing in distribution box
Electricity, ensure security.
In above-mentioned technical proposal, it is preferred that be equipped with cooling water pipeline on the casing.Casing is ensured using the structure
Interior radiating, prevent that local temperature is too high.
In above-mentioned technical proposal, it is preferred that the toggle switch is connected with wireless launcher.It can be passed through using the structure
Control terminal receives the signal that wireless transmitter is sent, so as to recognize the real-time status of distribution box, convenient monitoring and maintenance.
The present invention compared with prior art, has the advantages that：During this kind of explosion-proof electrical distribution box door opening state, cylinder
Push rod is in retracted mode, and now toggle switch is closed, and when distribution box needs to open, chamber door is closed, revolved by magnetic force
Gas in casing is pumped into compressed gas cylinder by button control air pump so that the gas in casing thins out, and casing is not easy to send out
Raw burning；Air pressure diminishes during gas is extracted out, and the push rod auto-extending of cylinder opens toggle switch, in the state
Under, the door of distribution box is because draught head is held out against, the unlatching that door can not be random, while under the state, if there is the feelings of gas leakage
The push rod of condition cylinder is retracted and distribution box way circuit is closed the driving lever of toggle switch to automatically automatically, ensures security；To open
When opening, control air pump that gas in compressed gas cylinder is put back into casing by magnetic force knob, now the push rod of cylinder contracts automatically
Return and distribution box way circuit is closed the driving lever of toggle switch to automatically, door can also be opened, so as to ensure to match somebody with somebody when casing is opened
Without electricity in electronic box, ensure security.
