Description
Technical field
Patent of the present invention relates to switch cubicle duplicate system, particularly to the transformer of a kind of band contact box.
Background technology
Transformer is the general designation of current transformer and voltage transformer, is used for measuring or protecting system, and its function is mainly
High voltage or big electric current scaling transformation are become normal low voltage or standard small area analysis, in order to realize measuring instruments, protection equipment
And the standardization of automatic controlling device, miniaturization, transformer may further be used to separate high-voltage system simultaneously, to ensure the person and to set
Standby safety.
Contact box in handcart switch cabinet is generally only used as installation and the insulating protection parts of static contact, and it includes one
Inner chamber, the conductor that the insulating body of intracavity bottom is through before and after being embedded with, conductor rear and front end is exposed, and is respectively intended to connect contact
And busbar.In generally there is provision of independent current transformer, its cabinet taken in switch cubicle, space is relatively big, to switch cubicle
Miniaturization brings difficulty, and after being connected with other electric elements, electrical body large area is exposed outside, has insulating properties low
Shortcoming.
Summary of the invention
The technical assignment of the technical problem to be solved and proposition is to improve prior art, it is provided that a kind of
With the transformer of contact box, take up room greatly it is intended that solve transformer with contact box, the shortcoming that insulating properties are low.
For solving above technical problem, the technical scheme is that, the transformer of a kind of band contact box, described transformer
Including wire and coil, overlapping cored around described wire, secondary coil is wrapped on iron core, insulate between wire and iron core,
Wire and iron core are provided around insulation crust, and secondary coil is connected with external circuit, outward by the second terminal on insulation crust
Loop, portion is connected to metering device, and the other end of insulation crust is provided with contact box, the static contact in contact box and wire one end
Connecting, the wire other end is connected with the conductor terminal on insulation crust.
Preferably, described insulation crust is provided with for installing fixing installing hole.
Preferably, the material that described insulation crust uses is specially epoxy resin mixed glue.
Preferably, insulation crust and contact box use epoxy resin mixed glue one moulding by casting.
Preferably, described contact box periphery is provided with flange mounting hole.
Preferably, the insulation crust below described contact box is provided with heat dissipation channel.
Preferably, the insulating barrier of raising breakdown voltage it is provided with below described heat dissipation channel.
According to the present invention, in circuit, electric current flows into transformer from stationary contact to the wired in series of transformer, through wire by
Conductor terminal flows out, and under the effect of electromagnetic induction, produces induced potential, form faradism by external circuit in secondary coil
Stream, external circuit is connected to instrumentation, relay protection and automaton.
Pour into entirety according to the present invention, transformer and contact box, reduce transformer and contact box institute in switch cubicle
The space taken, the insulation crust of one cast has more preferable insulating properties, and it is logical that the housing below contact box is provided with heat radiation
Road, heat radiation in time ensures the security performance of contact box, and the insulating barrier below heat dissipation channel improves breakdown voltage, has preferably
Electrical insulation properties.
Pour into entirety according to the present invention, transformer and contact box, have that to take the space of switch cubicle less, and preferably
The advantage of electric insulating quality.
