Abstract
The utility model discloses a kind of AC metal sealed switch apparatus with bypass functionality, include cabinet, to be arranged in cabinet and interconnective circuit breaker, on-load switch and earthed switch; Circuit breaker, on-load switch are connected with earthed switch respectively.The utility model structure is simple, processing and manufacturing cost is low, the basis of original AC metal sealed switch apparatus installs on-load switch additional, when circuit breaker will carry out safeguarding or keeping in repair, current earthing, circuit breaker shifts out after outside cabinet, and ground connection disconnects, and electric current switches to bypass through on-load switch, when circuit breaker keeps in repair, ensure that Electricity customers does not have a power failure.The utility model had both avoided the problem of interruption maintenance, simultaneously easy-to-operate, and cost is little, met basic Electricity customers and exempted from the requirement safeguarded or keep in repair that has a power failure.
Description
Technical field
The utility model relates to electric power complete set of equipments technical field, specifically a kind of AC metal sealed switch apparatus with bypass functionality.
Background technology
In 10KV switching system, need power failure to carry out safeguarding or keeping in repair when circuit breaker breaks down, inconvenience is brought to Electricity customers, also there is the technology such as dual-power automatic switching can realize the maintenance that do not have a power failure at present, but be often used for some important mechanism, as important departments such as government, steel mill, hospitals, equipment investment is simultaneously large, and general Electricity customers is difficult to burden.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of AC metal sealed switch apparatus with bypass functionality, adds the on-load switch that a group is played bypass effect; When circuit breaker will carry out safeguarding or keeping in repair, current earthing, circuit breaker shifts out after outside cabinet, and ground connection disconnects, and electric current switches to bypass through on-load switch, when circuit breaker keeps in repair, ensures that Electricity customers does not have a power failure.
The technical solution of the utility model is:
A kind of AC metal sealed switch apparatus with bypass functionality, include cabinet, to be arranged in cabinet and interconnective circuit breaker, earthed switch, on-load switch summation current transformer, described circuit breaker is connected with main bus bar, on-load switch is connected with hospital bus bar, circuit breaker, on-load switch are connected with earthed switch respectively, and current transformer is connected between circuit breaker and earthed switch.
Described on-load switch is SF
6on-load switch.
Advantage of the present utility model:
The utility model structure is simple, processing and manufacturing cost is low, the basis of original AC metal sealed switch apparatus installs on-load switch and hospital bus bar additional, when circuit breaker will carry out safeguarding or keeping in repair, current earthing, circuit breaker shifts out after outside cabinet, and ground connection disconnects, and electric current switches to bypass through on-load switch, when circuit breaker keeps in repair, ensure that Electricity customers does not have a power failure.The utility model had both avoided the problem of interruption maintenance, simultaneously easy-to-operate, and cost is little, met basic Electricity customers and exempted from the requirement safeguarded or keep in repair that has a power failure.
Accompanying drawing explanation
Fig. 1 is circuit theory diagrams of the present utility model.
Fig. 2 is structural representation of the present utility model.
Embodiment
See Fig. 1 and Fig. 2, a kind of AC metal sealed switch apparatus with bypass functionality, includes cabinet 1, is arranged at circuit breaker 2, SF in cabinet 1
6on-load switch 3, earthed switch 4 summation current transformer 5; Circuit breaker 2 is connected with main bus bar 6, SF
6on-load switch 3 is connected with hospital bus bar 7, circuit breaker 2, SF
6on-load switch 3 is connected with earthed switch 4 respectively, and current transformer 5 is connected between circuit breaker 2 and earthed switch 4, for measuring the electric current of main road.
Overhaul of line breaker shifts out process:
Circuit breaker 2 in normal operating conditions, SF
6on-load switch 3 is in the state of disconnection, and earthed switch 4 is in off-state; When circuit breaker 2 needs to safeguard or keep in repair, first the circuit breaker 2 being in off-state is moved to test position, then closed by earthed switch 4, then move to outside cabinet by circuit breaker 2, last earthed switch 4 disconnects, simultaneously SF
6on-load switch 3 closes, now just circuit is switched to hospital bus bar 7 from main bus bar 6, thus ensure that Electricity customers avoids having a power failure, now just the circuit breaker 2 that will safeguard can be safeguarded or be keeped in repair, by regulation flow operations, equipment being restored again after waiting maintenance to complete.
Claims (2)
1. the AC metal sealed switch apparatus with bypass functionality, include cabinet, to be arranged in cabinet and interconnective circuit breaker and earthed switch, it is characterized in that: in described cabinet, on-load switch summation current transformer is also set, described circuit breaker is connected with main bus bar, on-load switch is connected with hospital bus bar, and circuit breaker, on-load switch are connected with earthed switch respectively, and current transformer is connected between circuit breaker and earthed switch.
2. a kind of AC metal sealed switch apparatus with bypass functionality according to claim 1, is characterized in that: described on-load switch is SF
6on-load switch.
