Description

A kind of power distribution cabinet
Technical field
The present invention relates to electric fittings technical field, more particularly to a kind of power distribution cabinet.
Background technology
Switchgear typically refers to set the complete distribution that primary equipment, secondary device are assembled into one by certain predetermined circuit It is standby, it is mainly used for opening and closing, control and protecting each circuit and equipment, is widely used in power plant, substation, petrochemical industry, metallurgy The various different occasions such as steel rolling, industry light industry textile industry, industrial enterprise and residential quarters, skyscraper.
Under normal conditions, switchgear is busbar distribution cabinet, breaker power distribution cabinet, instrument power distributing cabinet and feedback by divides The parts such as line power distribution cabinet.It can facilitate when the circuit is operating normally and manually or automatically be connected using switchgear or disjunction circuit.Work as electricity It can also facilitate when road failure or irregular operating and cut off circuit by switchgear or send out alarm.In addition, being also may rely on out It closes each meter setting of cabinet and monitors certain electric parameters.
By taking breaker power distribution cabinet as an example, different type is usually mounted in breaker power distribution cabinet for carrying and opening and closing circuit The breaker of middle electric current, these breakers are usually divided into as air-break, leakage circuit breakers and double power-supply automatic transferring open circuit Device.
Existing breaker power distribution cabinet includes open type metal bin, is articulated with the metal at the open type metal bin edge Cabinet door and the cabinet door lock being installed between the open type metal bin and metal cabinet door.When breaker distribution is observed or adjusted to needs In cabinet when the working condition of each breaker, operating personnel need to usually open cabinet door lock first with key, and open simultaneously metal Cabinet door, operation is cumbersome, is unfavorable for the working condition of rapid examination and each breaker of adjustment.
In addition, again due to being directly connected by electric wire between each breaker in each breaker power distribution cabinet, cause electric wire with Connector lug leakage between each breaker, and corresponding insulating element and false hit portion are not set in breaker power distribution cabinet Part causes operating personnel that may induce the risk got an electric shock or powered off without reason when observing and adjusting the working condition of breaker, makes The safety for obtaining breaker power distribution cabinet decreases.
Therefore, existing power distribution cabinet has that inconvenient for operation and safety is poor.
Invention content
In view of this, the purpose of the present invention is to provide a kind of power distribution cabinet, safety is higher, operation is more convenient.
Its concrete scheme is as follows:
Power distribution cabinet provided herein, including:
Mounting plate has the mounting groove for accommodating electrical equipment;
The protective plate to fit with the edge of the mounting groove, the protective plate are equipped with for being passed through for electrical equipment Avoid holes;
The access panel being articulated on the mounting plate edge, the access panel are equipped with the observation for observing electrical equipment Hole.
Preferably, further include:
Set on the edge of the mounting plate, it is used to support first hinged group of the mounting plate relative to installation panel rotation Part;
For being set between the mounting plate and installation panel with relative to installation panel locking or the unlatching mounting plate The first door lock.
Preferably, further include:
It is connected between the mounting plate and the access panel, is used to support the access panel relative to the mounting plate turn The second dynamic hinge assembly.
Between the access panel and the protective plate, for relative to the protective plate locking or the unlatching observation Second door lock of plate.
Preferably, the mounting plate includes:
In the mounting groove, it is used to support the support plate of electrical equipment;
It is distributed in the side of the support plate, for the threading hole that passes through of line for connecting electrical equipment;
Set on the back side of the mounting groove, the tie pole for fixing line.
Preferably, the mounting plate further includes:
Between the protective plate and the support plate and it is fixedly arranged on the inner wall of the mounting groove, is described anti-for fixing The bearing of backplate.
Preferably, the protective plate includes:
It is fixed between the protective plate and the bearing, for the first both fixed fastening assembly.
Preferably, the access panel further includes:
It is installed on the peep hole, the transparent panel for separating electrical equipment with the external world.
Preferably, the access panel further includes:
It is fixed between the transparent panel and the access panel, for the second both fixed fastening assembly.
Preferably, second fastening assembly includes:
One end is each passed through the access panel with the transparent panel and the other end is to the close protective plate of the access panel Side extend, the fixed seat with central cavity;
The fastener being installed in the central cavity;
The briquetting of periphery with the step surface to offset with the transparent panel and set on the fixed seat;
The elastic washer to offset respectively with the briquetting and the fastener across the fastener and both ends.
Preferably, the cross section of the access panel between the cross section of the cross section of the mounting groove and the mounting plate it Between.
With respect to the background art, power distribution cabinet provided herein includes mounting plate, protective plate and access panel, wherein described There is mounting plate the mounting groove for accommodating electrical equipment, the protective plate to be equipped with the evacuation for being passed through for electrical equipment Hole, the access panel are equipped with the peep hole for observing electrical equipment.
Since each electrical equipment is installed in the mounting groove, and the outer of the protective plate and the mounting groove is affixed Close, the access panel is by being articulated with the edge of the mounting plate so that the root of electrical equipment be located at the mounting plate with it is described Between protective plate, top is across the avoid holes positioned at the protective plate and the access panel.
Since the operation button and instrument display panel of electrical equipment are usually provided in its top, the operation of natural electrical equipment is pressed Button and instrument display panel just leak outside between the access panel and the protective plate, and the access panel is equipped with the observation Hole, therefore when operating personnel need to observe the working condition of each electrical equipment, it is only necessary to it is observed, is not necessarily to by the peep hole The access panel and the protective plate are opened, simplifies operating process, is conveniently operated.
Again since each electrical equipment is mounted in the mounting groove, therefore the tie point of each electrical equipment and electric wire is just described Protective plate insulation blocking is got up, when operating personnel need to adjust or operate each electrical equipment, it is only necessary to open the access panel i.e. Can, without opening the protective plate, natural operating personnel can avoid leak source position or the mistake of touching junction in operation Other electrical equipments are touched, the risk got an electric shock and powered off without reason is reduced, safety just increases.
Therefore, the safety of power distribution cabinet provided herein is higher, operation is more convenient.
