Abstract
A kind of central switch cabinet earthed switch intelligent error preventing operating means, comprises switch cubicle; Be characterized in: in switch cubicle, be provided with intellectual status indicator 1, electromagnetic lock 2, earthed switch operation baffle plate 3; Export a secondary locking contact by intellectual status indicator 1 and act on electromagnetic lock 2, electromagnetic lock 2 controls earthed switch operation baffle plate 3 by lockweight.The utility model solves the practical difficulty in production work, based on functional, premised on fail safe, greatly increase work efficiency and work quality, solve the state of switch at " test cold standby ", must be closed earthed switch, Mechanically programm's locking could unlock, and opens the shortcoming of rear cabinet door electrical verification, enhances the fail safe of operation.
Description
Technical field
The utility model belongs to electrical network for transformation device, and what especially relate to earthed switch in central switch cabinet prevents charged misconnecting earthed switch.
Background technology
In the last few years, along with socioeconomic development, indoor high-voltage switch cabinet several times improved, and from fixing metallic armoured switch cabinet, developed into metal armouring middle and the units combination type combined switch cubicle of metal armouring of today.Be in " test/isolation " position when handcart or removing position, when this outgoing line cabinet line side be turned maintenance by cold standby, because judging whether this outlet line side has electricity can only judge with the display of electrification display.The dysfunction due to electrification display is found in actual motion, wrong will have electricity to be shown as no electricity, therefore, in actual motion, operations staff dare not using the display of electrification display as judging that line side there is not the foundation of electricity really, and need show after it does not have voltage according to electrification display, after again the screw on shrouding behind this feeder cabinet cable vault directly being turned on, pull down rear shrouding, with electrical verification rod, electrical verification is carried out to the exposed part of branch bar in cabinet, identify indeed after no-voltage, could in Gui Hou cable vault direct hanging earthing conductor.When outlet switch cabinet hidden danger of more times is larger, maximum potential safety hazard goes to the wrong way interval exactly, causes charged conjunction earthed switch.
Summary of the invention
The purpose of this utility model provides a kind of central switch cabinet earthed switch intelligent error preventing operating means to overcome the above problems exactly, and cost is low, safe and reliable, can in case charged conjunction earthed switch.
The purpose of this utility model is achieved like this: a kind of central switch cabinet earthed switch intelligent error preventing operating means, comprises switch cubicle; Be characterized in: in switch cubicle, be provided with intellectual status indicator, electromagnetic lock, earthed switch operation baffle plate; Export a secondary locking contact by intellectual status indicator and act on electromagnetic lock, electromagnetic lock controls earthed switch operation baffle plate by lockweight.
The utility model solves the practical difficulty in production work, based on functional, premised on fail safe, greatly increase work efficiency and work quality, solve the state of switch at " test cold standby ", must be closed earthed switch, Mechanically programm's locking could unlock, and opens the shortcoming of rear cabinet door electrical verification, enhances the fail safe of operation.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
In figure: 1, intellectual status indicator; 2, electromagnetic lock; 3, earthed switch operation baffle plate.
Embodiment
As shown in Figure 1, the utility model it comprise: the intellectual status indicator 1 in switch cubicle, switch cubicle, the electromagnetic lock 2 being positioned at switch cubicle, earthed switch operation baffle plate 3; Export a secondary locking contact by intellectual status indicator 1 and act on electromagnetic lock 2, electromagnetic lock controls earthed switch operation baffle plate 3 by lockweight.
The present invention can be applicable to the central switch cabinet of 10kV and 35kV.
