Description
Technical field
The utility model relates to instrument transformer applied technical field, is specially a kind of integral-casting combination transformer.
Background technology
Combination transformer is the instrument transformer be combined into one by current transformer and voltage transformer.Current combination transformer structure adopts following measures usually: 1. outdoor products structure, two element is pentastyle, and voltage transformer adopts V/V type connection, is connected in parallel on AB and CB alternate, current transformer is serially connected in A, C phase, is made up of two current transformers and two voltage transformers.An outlet terminal is that insulator and outsourcing silicon rubber umbrella skirt are composited, and profile adopts size rainproof full skirt, and surface creepage distance is large, and it is strong that ability is dodged in anti-overvoltage, anti-soil.2. casing is stainless steel or steel plate plastic-blasting, and secondary outgoing line is that Armor fills the construction of cable, and cabinet design has lead sealing, and anti-electricity-theft ability is strong.3, builtin voltage instrument transformer, current transformer adopt independent poured with epoxy resin.4, carry out secondary connection to be drawn out on a terminal and secondary terminals.
Major defect and the problem of employing Split type structure are:
Combination transformer inside adopts the voltage transformer summation current transformer of split cast, and back panel wiring adopts air insulation mode, because there was dampness in the air or dust pollution serious, easily causes insulation harm, internal discharge.Cause power outage; Adopt pentastyle to add Stainless Steel Shell structure installment space large, volume is comparatively large, and weight is large, is not easy to install; Combination transformer once occur insulation harm, easily cause stainless steel or metal shell charged, though there is ground protection also easily accident of human electric shock to occur; User's reverse graft back panel wiring can carry out stealing; Back panel wiring post may loosen.
Utility model content
The purpose of this utility model is to provide a kind of integral-casting combination transformer, and it can effectively solve Problems existing in background technology.
For achieving the above object, the utility model provides following technical scheme: a kind of integral-casting combination transformer, comprises flame-resistant high-temperature-resistant housing, current transformer and voltage transformer; Described current transformer and voltage transformer moulding by casting are on flame-resistant high-temperature-resistant housing.
Further, described current transformer iron core adopts non-crystaline amorphous metal new magnetic material.
Further, the combination transformer that described current transformer and voltage transformer are formed is totally-enclosed silicon rubber insulation structure.
Further, the secondary wiring terminals of described current transformer and voltage transformer installs stainless steel spring packing ring additional.
Further, the Inside coil joint of described current transformer and voltage transformer and copper binding post can adopt brazing by user's requirement
Compared with prior art, the beneficial effects of the utility model are: this integral-casting combination transformer, employing can be fire-retardant plastic casing, inner integrated poured instrument transformer silicon special rubber, adopt high-quality iron core, improve back panel wiring technique, improve measuring accuracy, improve safety system, the generation of minimizing accident; Overall structure is simple, practical, is easy to promote the use of.

In Reference numeral: flame-resistant high-temperature-resistant housing 1; Current transformer 2; Voltage transformer 3.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 ~ 3, the utility model provides a kind of technical scheme: a kind of integral-casting combination transformer, comprises flame-resistant high-temperature-resistant housing 1, current transformer 2 and voltage transformer 3; Described current transformer 2 and voltage transformer 3 moulding by casting are on flame-resistant high-temperature-resistant housing 1.
Further, described current transformer iron core adopts non-crystaline amorphous metal new magnetic material.
Further, the combination transformer that described current transformer 2 and voltage transformer 3 are formed is totally-enclosed silicon rubber insulation structure.
Further, the secondary wiring terminals of described current transformer 2 and voltage transformer 3 installs stainless steel spring packing ring additional.
Further, the Inside coil joint of described current transformer 2 and voltage transformer 3 and copper binding post can adopt brazing by user's requirement.
Of the present utility model when designing: to adopt flame-resistant high-temperature-resistant housing, improve machinery and the electrical strength of product.
Adopt instrument transformer silicon special rubber (double-component cold curing silicon rubber) vacuum casting process, it has nontoxic, corrosion-free, pollution-free, high temperature resistant, ageing-resistant, resistance to ozone, UV resistant, resistance to arcing and corona, resistance to general chemicals, moistureproof and waterproof is good, electrical insulation capability is good, have the superior functions such as certain anti-flammability.
Combination transformer adopts integrated poured, and user cannot carry out stealing by reconfiguration back panel wiring, effectively carries out anti-electricity-theft.
Current transformer iron core adopts non-crystaline amorphous metal new magnetic material, and the stability that its magnetic permeability is high, saturation magnetic induction is low and excellent, ensure that measuring accuracy during small area analysis, improves the coefficient of safety of instrument.Voltage transformer unit takes the close design of low specified magnetic, effectively improves the ability of the anti-system line resonance of product.
Combination transformer is totally-enclosed silicon rubber insulation structure, silicon rubber be cast under vacuum conditions can be fire-retardant plastic casing in, partial discharge quantity can control at below 10pC effectively, excellent insulating property, moisture proof, Maintenance free.Solve the problem of Cracking because of epoxy resin alternating hot and cold simultaneously, improve epoxy resin and copper cash because of the coefficient of expansion inconsistent, cause instrument transformer to insulate the hidden danger existed and the explosion issues caused.
Secondary wiring terminals installs stainless steel spring packing ring additional, and what prevent secondary wiring from causing because of thermal expansion or other factors loosens.
Inside coil joint and copper binding post can adopt brazing by user's requirement, make pad more firm, more reliably, solve because back panel wiring loosens the electricity dispute caused, solve the hidden danger in running and drawback.
Wiring shrouding adopts lead sealing, has anti-stealing electricity function.
Although illustrate and described embodiment of the present utility model, for the ordinary skill in the art, be appreciated that and can carry out multiple change, amendment, replacement and modification to these embodiments when not departing from principle of the present utility model and spirit, scope of the present utility model is by claims and equivalents thereof.
