Abstract
The present invention relates to a kind of mutual inductance device for temperature-control-low-voltage low-voltage circuit breaker, include shell, shell is provided with lid, shell is provided with wiring through hole, be provided with assembly housing region in shell, be characterized in: be provided with instrument transformer in assembly housing region, instrument transformer is provided with telecommunication cable.Meanwhile, communication cable perforation wiring through hole, is provided with Communication Interface Module in the termination of communication cable.Further, communication cable is provided with temperature-controlling module.Thus, by Communication Interface Module, can with the external device line curtain of plurality of specifications, instrument transformer necessary power output when well can not only ensure 0.4In, and the temperature rise when 1.0In can be ensured.Further, because heat is by moving outside heat radiation power resistance, so not only can extends the useful life of instrument transformer, and the certainty of measurement of instrument transformer can be improved.The material cost of instrument transformer can be reduced simultaneously.
Description
Technical field
The present invention relates to a kind of mutual-inductance apparatus, particularly relate to a kind of mutual inductance device for temperature-control-low-voltage low-voltage circuit breaker.
Background technology
Instrument transformer (instrumenttransformer) is the equipment of scaling transformation voltage or electric current.High voltage or big current scaling transformation are mainly become normal low voltage (100V) or standard small area analysis (5A or 1A by its function; all refer to rated value), to realize standardization, the miniaturization of measuring instrument, proterctive equipment and automatic control equipment.Instrument transformer also can be used to separate high-voltage system simultaneously, to ensure the safety of the person and equipment.The equipment of scaling transformation voltage or electric current.
But, because power output enough when fast saturated instrument transformer not only will ensure 0.4In, and to ensure that the temperature rise when 1.0In again can not be too high.Therefore original instrument transformer must make many specifications, i.e. the corresponding a kind of instrument transformer of each rated current, and ability is head it off reluctantly, and nonetheless the temperature rise of instrument transformer can not be well controlled.
Summary of the invention
Object of the present invention is exactly to solve the above-mentioned problems in the prior art, provides a kind of mutual inductance device for temperature-control-low-voltage low-voltage circuit breaker.
Object of the present invention is achieved through the following technical solutions:
A kind of mutual inductance device for temperature-control-low-voltage low-voltage circuit breaker, include shell, described shell is provided with lid, described shell is provided with wiring through hole, is provided with assembly housing region in described shell, is provided with instrument transformer in described assembly housing region, described instrument transformer is provided with telecommunication cable, described telecommunication cable perforation wiring through hole, the termination of described telecommunication cable is provided with Communication Interface Module, and described telecommunication cable is provided with temperature-controlling module; Described telecommunication cable is provided with wiring trip, described temperature-controlling module is provided with Wiring button, described wiring trip embeds in Wiring button; Described telecommunication cable includes input channel cable and output channel cable, and described input channel cable is provided with temperature-controlling module, or, described output channel cable is provided with temperature-controlling module; Described temperature-controlling module is plug-in type power resistor; Metallic channel is provided with in described shell; Locating fastener is provided with in described shell; Sealing ring is provided with between described shell and lid.
The advantage of technical solution of the present invention is mainly reflected in: pass through Communication Interface Module, can with the external device line curtain of plurality of specifications, instrument transformer necessary power output when well can not only ensure 0.4In, and the temperature rise that can ensure when 1.0In, make the temperature rise of instrument transformer be significantly less than the instrument transformer of old technical scheme.Further, because heat is by moving outside heat radiation power resistance, so not only can extends the useful life of instrument transformer, and the certainty of measurement of instrument transformer can be improved.The material cost of instrument transformer can be reduced simultaneously, be easy to manufacture.
