Abstract
The utility model discloses a kind of combination transformer, including voltage transformer, current transformer and high-tension fuse, one end of voltage transformer primary side is used for phase-connecting wire or as neutral end, one end of the other end connection high-tension fuse of voltage transformer primary side, one end of the other end connection current transformer primary side of high-tension fuse.The utility model voltage transformer part carries high-tension fuse, has autoprotection function.Current transformer and voltage transformer are connected together, installation is simplified and changes inspection operation, the problems such as effectively prevent after installation distance and creep age distance deficiency between original paper.
Description
Technical field
Transformer is the utility model is related to, more particularly to a kind of combination transformer.
Background technology
Transformer is that metering is realized in electric power meter systems, monitoring, the original paper of protection.What is used at present in power system is mutual
Sensor only needs 4-6 transformer to be fitted together to be single, installation is complicated, after difficult, installation of changing maintenance between original paper distance and
The problems such as creep age distance deficiency.Other product can not install fuse or can only select the problem of external fuse perplexs electricity all the time
Force system use and maintenance attendant.
Utility model content
Purpose of utility model：The purpose of this utility model, which is to provide, a kind of can solve the problem that defect present in prior art
Combination transformer.
Technical scheme：Combination transformer described in the utility model, including voltage transformer, current transformer and high-voltage fuse
Disconnected device, one end of voltage transformer primary side are used for phase-connecting wire or as neutral end, the other end of voltage transformer primary side
Connect one end of high-tension fuse, one end of the other end connection current transformer primary side of high-tension fuse.
Further, the Current Transformer Secondary side includes two independent windings.So pass through this combination mutual inductance
Device just can meet the needs of different no-load voltage ratios, avoid the need for multiple transformers being installed together, so as to simplify installation and change
Inspection operation, the problems such as effectively prevent after installation distance and creep age distance deficiency between original paper.And can be mutual by two combinations
Sensor carries out " V " shape wiring, three combination transformers can also be carried out into Y-shaped wiring, the mode of connection is flexible.
Further, one end of the voltage transformer primary side, the both ends of current transformer primary side are from combination mutual inductance
Passed at the top of device, all of the port of all of the port summation current transformer secondary side of voltage transformer secondary side is from combination mutual inductance
Device bottom passes.
Further, protective cover is provided between the voltage transformer secondary side and Current Transformer Secondary side.So can
Effectively prevent that worm damaged by rats is broken and the phenomenon of other people stealings.
Beneficial effect：The utility model discloses a kind of combination transformer, voltage transformer part carries high-tension fuse,
With autoprotection function.Current transformer and voltage transformer are connected together, installation is simplified and changes inspection operation, have
Effect avoids after installation the problems such as distance and creep age distance deficiency between original paper.

Embodiment
With reference to embodiment and accompanying drawing, the technical solution of the utility model is described further.
The utility model discloses a kind of combination transformer, as depicted in figs. 1 and 2, including voltage transformer, Current Mutual Inductance
Device and high-tension fuse 2, the B (N) of voltage transformer primary side are held for phase-connecting wire or as neutral end, voltage transformer one
One end of the other end connection high-tension fuse 2 of secondary side, the P1 of the other end connection current transformer primary side of high-tension fuse 2
End.The P1 ends and P2 ends of current transformer primary side are phase terminal, Current Transformer Secondary side include two it is independent around
Group, namely the first winding and the second winding, two output ends 1S1 and 1S2 of the first winding are defeated for the metering of current transformer two level
Go out end, two output ends 2S1 and 2S2 of the second winding are current transformer two level metering protection output end.The magnetic of first winding
The magnetic core 31 of the winding of core 32 and second is as shown in Figure 5.Voltage transformer secondary side has two output ends, namely a ends and b ends.Can
So that two combination transformers are carried out into " V " shape wiring, three combination transformers can also be subjected to Y-shaped wiring, the mode of connection
Flexibly.
Combination transformer by epoxy resin by voltage transformer, the summation current transformer moulding by casting of high-tension fuse 2, such as
Shown in Fig. 2-4, one end of voltage transformer primary side, the both ends of current transformer primary side are worn at the top of combination transformer
Go out, all of the port of all of the port summation current transformer secondary side of voltage transformer secondary side is from combination transformer bottom A
Opening position passes, as shown in Figure 2.
In order to prevent worm damaged by rats broken and other people stealings, between voltage transformer secondary side and Current Transformer Secondary side also
Protective cover can be provided with.
