Specific embodiment
To enable the purpose of the present invention, feature, advantage more obvious and understandable, implement below in conjunction with the present invention
Attached drawing in example, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that reality disclosed below
Applying example is only a part of the embodiment of the present invention, and not all embodiment.Based on the embodiments of the present invention, this field is common
Technical staff's all other embodiment obtained without making creative work belongs to the model that the present invention protects
It encloses.
It please refers to shown in Fig. 1 and Fig. 2.
It is a kind of not have a power failure the metal armoured switchgear of function with maintenance, including for installing the secondary of secondary component
Room 13, the first bus-bar room 11 for installing the first bus 21, the second bus-bar room 12 for installing the second bus 22, for pacifying
The circuit breaker cart room 14 of dress circuit breaker cart 26,15 and of current transformer handcart room for installing current transformer handcart 27
For installing the outlet room 16 of outlet service cable 29.
Specifically, secondary component includes secondary terminals row, instrument and protective device etc..
First bus-bar room 11 and the second bus-bar room 12 have respectively further comprised support insulator.
Circuit breaker cart 26 is for installing breaker 33, can be by will be breaking when needing to overhaul or replacing breaker 33
Device handcart 26 exits, and is overhauled or is replaced so that breaker 33 exits.
Current transformer handcart 27 is mutual when needing to overhaul or replacing electric current for installing current transformer (not shown)
When sensor, it can be overhauled or be replaced so that current transformer exits by exiting current transformer handcart 27.
Outlet service cable 29 is used for external power supply.
Specifically, the first bus 21 is connected with the first bus isolating switch 23, the second bus 22 be connected with the second bus every
Leave pass 24.
Therefore, when there is any one bus 100 to break down or need to overhaul, kept apart by switching corresponding bus
200 are closed to carry out guarantor's power supply.For example, first bus isolating switch 23 closes a floodgate, by the first bus 21 when the power supply of the first bus 21
Electric energy be sent to breaker 33, at this point, 24 separating brake of the second bus isolating switch.When handover is needed, the first bus is kept apart
23 separating brakes are closed, the second bus isolating switch 24 closes a floodgate, so that the electric energy of the second bus 22 is sent to breaker 33.
Therefore, 22 mutual backup of the first bus 21 and the second bus.
Further, breaker 33 includes upper touch base 31 and lower touch base 32, the feed motion of breaker 33, so that upper touch base
31 connect with lower touch base 32, the separating brake movement of breaker 33, so that upper touch base 31 and lower touch base 32 disconnect.
When breaker 33 needs to overhaul, if circuit breaker cart 26 exits, current supply circuit is disconnected at this time, outlet supply lines
There is no voltage on cable 29.
Therefore, in order to the maintenance or replacement of the realization breaker 33 in the case where not having a power failure, the upper touching of breaker 33
Seat 31 and lower touch base 32 are separately connected the both ends of disconnector 25.
When working properly, electric energy is exported via breaker 33, and disconnector 25 is in gate-dividing state at this time.When
When breaker 33 needs to overhaul or replace, first disconnector 25 is closed, is then exited circuit breaker cart 26, electric energy
It is exported via disconnector 25.
Further, the primary side end of incoming cables of current transformer is connected to the lower touch base 32 of breaker 33, current transformer
Primary side leading-out terminal be connected to outlet service cable 29.
In order to enable current transformer maintenance or replacement are convenient, in the present embodiment, it is mutual that current transformer is mounted on electric current
In sensor handcart 27.
Current transformer disconnecting switch 28 is installed in the primary side of current transformer.Specifically, current transformer is isolated
The both ends of switch 28 are connected to the lower touch base 32 and outlet service cable 29 of breaker 33.
Therefore, when working properly, the primary side of electric energy streams overcurrent mutual inductor, and export to outlet power cable 29.
When current transformer needs to overhaul or replace, current transformer disconnecting switch 28 is closed, and exit current transformer handcart 27,
Electric energy is exported via current transformer disconnecting switch 28 to outlet power cable 29.
Further, in the present embodiment, when connecting between all parts, busbar connection can be used.Specifically, this has
The metal armoured switchgear for overhauling the function that do not have a power failure further includes connection conductor 30, and the connection conductor 30 is described for connecting
First bus isolating switch 23, second bus isolating switch 24, the breaker 33 and the disconnector 25.
