Entirely, failure always occurs.Such as 10KV high-tension switch cabinet can encounter the influence due to ambient humidity in normal operation and cause
The decreasing insulating of insulating part, thus occur high-tension switch cabinet it is alternate or relatively electric discharge generate arc light, prolonged arc light
Electric discharge cause high-tension switch cabinet short circuit even explode, cause any property loss even casualties serious accident.
Therefore, how a kind of safe and reliable arc protection high-tension switch cabinet is provided, is that those skilled in the art urgently solve
A technical problem certainly.
Utility model content
The utility model provides a kind of arc protection high-tension switch cabinet, to solve the above technical problems.
In order to solve the above technical problems, the utility model provides a kind of arc protection high-tension switch cabinet, including cabinet body, it is described
Cabinet body inner route clapboard is divided into several for accommodating the compartment of electrical equipment, and the electrical equipment is unified by a power supply
It powers, at least one arc photosensor is equipped in each compartment, each arc photosensor and an arc protection fill
Set connected, each arc light protecting device is connected with a breaker respectively, and the breaker is connect with the power supply.
Preferably, each arc photosensor is also connect with a display unit, the display unit shows that arc light generates
Position.
Preferably, the arc photosensor uses fibre optical sensor.
Preferably, generating to the time of the circuit breaker trip power supply from arc light less than 100ms.
Preferably, being connected between the arc photosensor and the arc light protecting device using optical cable.
Compared with prior art, arc protection high-tension switch cabinet provided by the utility model, including cabinet body, in the cabinet body
It is divided into several by partition to be powered for accommodating the compartment of electrical equipment, the electrical equipment by a power supply is unified,
At least one arc photosensor, each arc photosensor and an arc light protecting device phase are equipped in each compartment
Even, each arc light protecting device is connected with a breaker respectively, and the breaker is connect with the power supply.This is practical
It is novel to utilize with the presence or absence of electric discharge arc light in each compartment of arc photosensor real-time detection, and at any time using arc light protecting device
Power supply isolated fault is cut off, so that the danger that arc short-circuit generates is maintained at minimum level.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of arc protection high-tension switch cabinet in one specific embodiment of the utility model.
In figure：10- cabinet body, 20- compartment, 30- arc photosensor, 40- arc light protecting device, 50- breaker, 60- are aobvious
Show unit.
Specific embodiment
To keep the above objects, features, and advantages of the utility model more obvious and easy to understand, with reference to the accompanying drawing to this
The specific embodiment of utility model is described in detail.It should be noted that the utility model attached drawing is all made of simplified form

The power supply connection.The utility model is interior with the presence or absence of electric discharge using each compartment 20 of 30 real-time detection of arc photosensor
Arc light, and power supply isolated fault is cut off at any time using arc light protecting device 40, thus the dangerous guarantor that arc short-circuit is generated
It holds in minimum level.
Preferably, with continued reference to FIG. 1, each arc photosensor 30 is also connect with a display unit 60, it is described aobvious
Show the position that unit 60 shows that arc light generates, to realize fault fast positioning, saves personnel's repair time.
Preferably, in the present embodiment, the arc photosensor 30 uses fibre optical sensor, and the arc light detecting time is short, precision
It is high；Preferably, being connected between the arc photosensor 30 and the arc light protecting device 40 using optical cable, signaling rate
Fastly, the time cut off the power to the breaker 50 is generated from arc light less than 100ms, it is ensured that entire arc light protection system moves
Make the time far faster than conventional protective device, avoid the influence due to ambient humidity and lead to the decreasing insulating of insulating part,
High-tension switch cabinet to occur is alternate or relatively electric discharge leads to the problem of arc light.
In conclusion arc protection high-tension switch cabinet provided by the utility model, including cabinet body 10, in the cabinet body 10 by
Partition is divided into several and is powered for accommodating the compartment 20 of electrical equipment, the electrical equipment by a power supply is unified,
At least one arc photosensor 30 is equipped in each compartment 20, each arc photosensor 30 and an arc protection fill
It sets 40 to be connected, each arc light protecting device 40 is connected with a breaker 50 respectively, the breaker 50 and the power supply electricity
Source connection.The utility model whether there is electric discharge arc light, and benefit using each compartment 20 of 30 real-time detection of arc photosensor is interior
Power supply isolated fault is cut off at any time with arc light protecting device 40, so that the danger that arc short-circuit generates is maintained at minimum water
It is flat.
