Abstract
The utility model discloses a switchgear room locking barrier, and belongs to the switchgear room barrier field. The switchgear room locking barrier comprises a switchgear room transformer and a barrier, and is characterized in that a DC rectification power supply is disposed at a secondary side of the switchgear room transformer, an output terminal of the DC rectification power supply is connected with an electromagnetic lock disposed on a barrier door, and the electromagnetic lock is in locking relationship with the secondary side of the switchgear room transformer. When the switchgear room transformer is operated, the electromagnetic lock is powered by the DC rectification power supply to lock the barrier door; and when the switchgear room transformer stops operating, the DC rectification power supply is powered off, the electromagnetic lock is reset, and then the barrier door can be opened. After the locking is developed successfully, a traditional barrier management mode for a high-voltage room of a rural switchgear room at present can be changed, safety hidden trouble can be effectively prevented, and therefore personal and equipment accidents can be prevented from happening. Through an optimization design, the switchgear room locking barrier is simple in structure and convenient to use, and a new technology usage mode is provided for standardization management of rural switchgear rooms.
Description
Technical field
The utility model provides a kind of switchgear house locking cover bar, belongs to switchgear house cover bar field.
Background technology
Rural power distribution chamber high-tension room cover bar is to prevent staff or equipment-patrolling personnel, is strayed into the electrification in high voltage zone, and by hanging warning sign, the protector that personnel are limited to warning has strict requirement and regulation in rural power technical regulation.
Existing cover bar can not meet this demand:
1, the requirement that rural area standardization switchgear house intelligence is built.Within 2012, rural power section of Zibo Power Supply Company proposes to accelerate the construction of rural intelligent power distribution chamber, effectively in conjunction with scientific and technological achievement, improves the switchgear house operation and management level.And the chamber of rural power distribution at present high-tension room is traditional wooden placed type cover bar, the tour personnel, for convenience of checkout facility, often move and enter, and very easily cause personal equipment casualty accident.
2, the requirement of equipment and personal safety.The chamber of rural power distribution at present high-tension room cover bar is traditional placed type, and the tour personnel, for convenience of checkout facility, often move and enter, and serious breach of security rules requirement, very easily cause personal equipment breakdown.
3, the requirement of marketing synergy extra earning work.For preventing client's stealing, rural comprehensive switchgear house step down side has been installed Box for avoiding fraudulent use of electricity, and in order to check meter, the staff moves at any time cover bar and enters and check meter, and its personal safety has been caused to great hidden danger.
From with, if can develop a kind of novel cover bar of utilizing locking to be controlled, the personnel of preventing enter, effectively the generation of Accident prevention.
The utility model content
According to above deficiency of the prior art, problem to be solved in the utility model is: provide a kind of simple in structure, use safety, during the operation of switchgear house transformer, can not open the switchgear house locking cover bar that forms locking.
The utility model solves the technical scheme that its technical problem adopts: a kind of switchgear house locking cover bar, comprise switchgear house transformer and cover bar, it is characterized in that: the switchgear house Circuit Fault on Secondary Transformer arranges DC rectification power, the output of DC rectification power connects electromagnetic lock, electromagnetic lock is arranged on the cover bar door, and electromagnetic lock and switchgear house Circuit Fault on Secondary Transformer are latching relation.
During the operation of switchgear house transformer, the DC rectification power power supply makes electromagnetic lock locking cover bar door; When the switchgear house transformer is out of service, the DC rectification power outage, electromagnetic lock resets, and now can open the cover bar door.
Wherein preferred version is:
Described DC rectification power comprises sampling transformer, half-wave rectifier bridge and filter capacitor, the sampling transformer is arranged on the cable of switchgear house Circuit Fault on Secondary Transformer, the output of sampling transformer connects half-wave rectifier bridge, and the output of half-wave rectifier bridge arranges filter capacitor.The sampling transformer gathers switchgear house Circuit Fault on Secondary Transformer running status, and provides power supply to supply with electromagnetic lock.
Described DC rectification power comprises three sampling transformers, is separately positioned on the three-phase cable of switchgear house Circuit Fault on Secondary Transformer.But while running into 1 fuse accidental, locking also can normally closed, but two-phase is charged in addition, if the staff enters, just have Danger Electric shock risk, therefore changing the circuit of this locking into three phase half wave rectification is direct current supply, only has fuse all to come off, locking just can be opened, and has prevented the generation of Issues on Static Electrification.
Compared with prior art, the beneficial effect that this switchgear house locking cover bar has is: by the switchgear house Circuit Fault on Secondary Transformer, DC rectification power is set, the output of DC rectification power connects electromagnetic lock, electromagnetic lock is arranged on the cover bar door, electromagnetic lock and switchgear house Circuit Fault on Secondary Transformer are latching relation, during the operation of switchgear house transformer, the DC rectification power power supply makes electromagnetic lock locking cover bar door; When the switchgear house transformer is out of service, the DC rectification power outage, electromagnetic lock resets, and now can open the cover bar door.After this locking is succeeded in developing, can solve the traditional cover bar management mode of current rural power distribution chamber high-tension room, the tour personnel can't arbitrarily move and enter, this is to reduce because of false touch and touch charging equipment by mistake from the human factor aspect, brought into play very large effect, potential safety hazard effectively prevented, thereby avoids the generation of personal equipment breakdown.Changde power administration person fatal accident of take is example, and responsibility related personnel's punishment just reaches more than 170,000 yuan, and it is higher that the dead compensates number.
Pass through optimal design, the utility model is simple in structure, easy to use, for the standardized management of rural power distribution chamber, a kind of new utilization mode is provided, has broken traditional concept for many years, improved the standardized management level, rural area standardization switchgear house management to carrying out at present, have very large promotional value.Due to the solution of anti-electricity-theft problem, also for enterprise's synergy extra earning, provide powerful guarantee in addition.
The accompanying drawing explanation
Fig. 1 is the functional-block diagram of the utility model embodiment;
Fig. 2 is the circuit theory diagrams of the utility model embodiment;
Wherein, 1, switchgear house transformer 2, sampling transformer 3, half-wave rectifier bridge 4, filter capacitor 5, electromagnetic lock 6, cover bar door.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
Embodiment 1:
As shown in Figure 1, switchgear house transformer 1 secondary side arranges DC rectification power, and the output of DC rectification power connects electromagnetic lock, and electromagnetic lock is arranged on cover bar door 6, and electromagnetic lock 5 is latching relation with the switchgear house Circuit Fault on Secondary Transformer.
