Technical field
This utility model is related to one kind and hauls oneself willingly into relay protective scheme checking device, belongs to electric power repair equipment technical field.
Background technology
Backup auto-activating device can automatically promptly by in-put of spare power supply work it is ensured that continuous power transmission.Backup auto-activating device is
One of visual plant of guarantee system safe and stable operation.Therefore periodic check must be carried out to backup auto-activating device, to ensure it
Normal operation.
Field-checking backup auto-activating device typically requires 3 people's cooperations and just can complete：One people is responsible for Operational Test Equipment and observes
The action situation of backup auto-activating device, a people is responsible for drawing busbar voltage air switch, and a remaining people is responsible for for switch position signal passing to guarantor
Protection unit.So not only waste of manpower, mismate between also tending to because of personnel, make backup auto-activating device akinesia.In addition, outlet
It is also possible to because loop causes power failure overlong time extremely during loop check.
Utility model content
This utility model purpose is to provide one kind to haul oneself willingly into relay protective scheme checking device, by protection device open entry loop even
Connect the device that the position of the switch is provided, intuitively reflect switch breaker tripping and closing position using display lamp, whole secondary circuit can be verified,
Visual result accurately, shortens the work power off time such as protective calibration or protection device transformation, efficiently solves background technology
Present in the problems referred to above.
The technical solution of the utility model is：One kind hauls oneself willingly into relay protective scheme checking device, comprises working power, protection dress
Put, power supply air switch, closing relay coil, separating brake relay coil, the position of the switch instruction and the position of the switch no source contact,
Described working power passes through power supply air switch, respectively with one end of closing relay coil and one end of separating brake relay coil
Connect, closing relay coil, separating brake relay coil the other end mutual with the breaker tripping and closing outlet loop of protection device respectively
Connect, the position of the switch no source contact is interconnected with the breaker tripping and closing open entry loop of protection device, position of the switch instruction is continued with combined floodgate
Electric apparatus coil, separating brake relay coil interconnect.
The instruction of the described position of the switch is provided with separating brake display lamp and combined floodgate display lamp.
The beneficial effects of the utility model are：Structure is simple, and operational approach is simple, and this utility model is by three switch modules
Composition, structure is simple, when using, only need to be connected tripping coil with outlet loop, no source contact is connected with open entry loop
?；Visual result, this utility model directly indicates switch breaker tripping and closing situation by display lamp, is tested in background technology
Instrument operates and checks that the staff of action situation may directly learn that result；Saving of work and time, needs 3 people to complete in background technology
Work, can be completed by 2 people using this utility model, will switch position signal pass to protection device work can by this
Utility model is automatically performed, and so, not only decreases the backup auto-activating device misoperation number of times leading to due to personnel's cooperation, simultaneously
Save checking time, improve verification efficiency；Complete survey whole secondary circuit logic, this utility model can be in the feelings that do not have a power failure
Under condition, check whole secondary circuit logical correctness, do the whole group transmission having a power failure after confirmation is errorless again, when substantially reducing power failure
Between, indirectly improve economic benefit.
