Formula can use more copper bus-bar, be unfavorable for the control of cost.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided be capable of the metal armouring of very big reduces cost
Moveable high-voltage switchgear measures mutual inductor installation structure.
To achieve these goals, the technical solution adopted in the utility model is：
This kind of metal-clad moveable high-voltage switchgear measures mutual inductor installation structure, including metering current mulual inductor and meter
Amount voltage transformer, the metering current mulual inductor is arranged in the bus room of high-tension switch cabinet, the metering current mulual inductor
With the main busbar connection of level in bus room；The metered voltage transformer is arranged on the rear lower interior of high-tension switch cabinet, described
Metered voltage transformer is connected with the main busbar of level.
The primary connection post of the metering current mulual inductor and the main busbar connection of level.
The metered voltage transformer is connected by connecting copper bar with the main busbar of level.
The utility model has the advantage of：The utility model metal-clad moveable high-voltage switchgear metering transformer is installed
Structure, the main busbar connection of level of the metering current mulual inductor directly and in bus room；Metered voltage transformer is located at rear lower interior,
Connected using connecting copper bar and main busbar, the use of main busbar can greatly be reduced, being capable of greatly reduces cost.

Specific embodiment
Below against accompanying drawing, by the description to optimum embodiment, specific embodiment of the present utility model is made into one
Step detailed description.
As shown in figure 1, this kind of metal-clad moveable high-voltage switchgear measures mutual inductor installation structure, including metering current
Transformer 2 and metered voltage transformer 3, metering current mulual inductor 2 is CT, and metered voltage transformer 3 is PT；Metering current mutual inductance
Device 2 is arranged in the bus-bar room 4 of high-tension switch cabinet, and the main busbar 1 of level in metering current mulual inductor 2 and bus-bar room 4 connects；Meter
Amount voltage transformer 3 is arranged in the rear lower room 5 of high-tension switch cabinet, and metered voltage transformer 3 is connected with the main busbar 1 of level.
After the installation site of metering current mulual inductor 2 and metered voltage transformer 3 is improved, the main busbar 1 of level first directly and
The connection of completion system by the connection of metering current mulual inductor 2, it is not necessary to again by the level master connected with metering current mulual inductor 2
Busbar 1 is accomplished to be connected with other switch cubicles by way of lower end is got in touch with the front lower room 6 of cabinet.Metered voltage transformer 3 is installed on
Room 5 is descended afterwards, is capable of achieving to be connected with main busbar by the less copper bar of sectional area.Which save the big master of more sectional area
Busbar, is saved greatly cost.
Further, the main busbar 1 of primary connection post and level of metering current mulual inductor 2 connects.The main busbar 1 of level is first straight
Connect the connection for being fixed on completion system by the primary connection post of metering current mulual inductor 2 connects, it is not necessary to busbar is done to cabinet
It is connected with other switch cubicles by way of lower end is got in touch with lower room 6, it is cost-effective.
Further, metered voltage transformer 3 is connected by connecting copper bar with the main busbar 1 of level.Metered voltage transformer 3
In rear lower room 5, connected using connecting copper bar and main busbar, by the adjustment of installation site, the length of main busbar much will
Less than the main busbar adopted in prior art, can greatly reduces cost.
This kind of metal-clad moveable high-voltage switchgear measures mutual inductor installation structure, metering current mulual inductor 2 directly and
The main busbar 1 of level in bus-bar room 4 connects；Metered voltage transformer 3 is located in rear lower room 5, using connecting copper bar and main busbar
Connection, can greatly reduce the use of main busbar.The installation site of the metering transformer of fixedly mounted metering, only using phase
When cabinet width length main busbar can completion system connection, being capable of greatly reduces cost.
Obviously the utility model is implemented and is not subject to the restrictions described above, as long as employing method of the present utility model
The improvement of the various unsubstantialities that design and technical scheme are carried out, within protection domain of the present utility model.
