Description
Technical field
The utility model is related to a kind of metering cabinets.
Background technology
In high-tension switch cabinet, according to the requirement that design institute designs, the metering cabinet designed in some systems is metering hand
The structure of vehicle, but some, in order to cost-effective, some is designed as metering cabinet and form is fixedly mounted, for metering handcart form
Switchgear, with regard to fairly simple when designing copper bar, as long as metering handcart is designed, as the switchgear of other breaker forms
Equally.But the switchgear of form is fixedly mounted for metering cabinet, with regard to relatively difficult when design, because should consider electric current
The fixed installation of mutual inductor and voltage transformer, again in view of the trend of copper bar, it is also contemplated that safe distance etc. is some other
Problem.
Utility model content
The goal of the invention of the utility model is：A kind of topology layout advantages of simple, structure are provided to solve problem above
Compact metering cabinet.
The technical solution adopted in the utility model is such：
Metering cabinet, including voltage transformer, current transformer and fuse,
There are two the voltage transformer and current transformer are equal, middle standing pillar both sides are fixed on by installing plate respectively；
One voltage transformer A ends are alignd with the A phase copper bars of switchgear, B ends and the switchgear C of another voltage transformer
Phase copper bar aligns, then is connected at the B ends of two voltage transformers with A ends by the row of connection, perforate and switchgear B among connection row
It aligns；
The center of two current transformers aligns respectively with A, C of switchgear, and molecule busbar is distinguished in switchgear A, C phase
It is connected with two current transformer P2 ends, switchgear A, C phase second line of a couplet complex molecule busbar is connected with the P1 ends of current transformer；It opens
Molecule busbar in cabinet B phases is closed to be directly connected to second line of a couplet complex molecule busbar；Fuse upper end passes through upper connection row and upper molecule busbar
Connection, lower end pass through connection row connection between lower connection row and two voltage transformers.
Further, molecule busbar is connected with second line of a couplet complex molecule busbar by the row of connection in switchgear B phases, which comes
Corresponding switchgear B-phase is put to be supported with insulator and be fixed.

In conclusion due to the adoption of the above technical scheme, the beneficial effects of the utility model are：
The utility model metering cabinet is laid out advantages of simple, and structural member gathers.
Description of the drawings
Fig. 1 is the structure chart of the utility model.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
As shown in Figure 1, metering cabinet, including voltage transformer 1, current transformer 2 and fuse 3,
The voltage transformer 1 and current transformer 2 there are two, middle standing pillar two is fixed on by installing plate respectively
Side；
One voltage transformer 1A ends are alignd with the A phase copper bars of switchgear, B ends and the switch of another voltage transformer 1
Cabinet C phases copper bar aligns, then is connected at the B ends of two voltage transformers 1 with A ends by the row of connection, and perforate is with opening among connection row
Cabinet B is closed to align；
The center of two current transformers 2 aligns respectively with A, C of switchgear, facilitates connection, divides in switchgear A, C phase
Primary and secondary line 4 is connected respectively with two current transformer 2P2 ends, switchgear A, C phase second line of a couplet complex molecule busbar 5 and current transformer 2
P1 ends be connected；For intermediate B phases, without current transformer 2, directly connected using insulator support from upper molecule busbar 4
To second line of a couplet complex molecule busbar 5；In order to gather signal, in 2 right side installation sensor 6 of current transformer, connected and arranged by sensor 6
It is connected with current transformer 2.
3 upper end of fuse is arranged 7 by upper connection and is connected with upper molecule busbar 4, and 8 and two voltages are arranged in lower end by lower connection
Connection row connection between mutual inductor 1.
Molecule busbar 4 is connected with second line of a couplet complex molecule busbar 5 by the row of connection in switchgear B phases, which comes correspondence and open
Cabinet B-phase is closed to put with the support fixation of insulator 9.
In the upper end of 2 installing plate of current transformer, three insulators 9 are installed, for fixing connection row 7 on fuse 3.
Since the lower connection row 8 of fuse 3 selects the copper bars of 30*3, size is big, and long, it is contemplated that usually
Vibration can be generated during use, fuse 3 is it is possible that can drop, in the place increase close to fuse 3 when design
Insulator 9 is fixed, and in two side opening of secondary wire slot, can be installed insulator 9 and be fixed support, copper bar is fixed on insulator 9.
In order to ensure that A, C phase copper bar to the safe distance of middle standing pillar, install two pieces of insulation boards on middle standing pillar, it is ensured that
Securely and reliably.
The above is merely intended for describing the technical solutions of the present application, but not for limiting the present application, those of ordinary skill in the art couple
The other modifications or equivalent substitution that the technical solution of the utility model is made, without departing from technical solutions of the utility model
Spirit and scope should all cover among the right of the utility model.
