Description
Technical field
The utility model is related to field of electrical equipment, specifically, is related to a kind of waterproof Open Type Electric Current Mutual Inductor.
Background technology
Current transformer is one of device for commonly using in electrical power distribution, monitoring, protection, measuring system, for by circuit
High current, high voltage signal, the completely isolated low current of circuit, low voltage signal are transformed to and are transformed, so as to secondary instrument
Table and equipment are monitored, measure or controlled to the high voltage in circuit, high current.Current transformer plays conversion electric current
With the effect of electrical isolation, it is easy to secondary device and instrument to carry out signal transacting and avoids the danger of direct measurement circuit.
When conventional current transformer is applied to existing distribution system transformation project, first deenergization, dismounting bus, mother are needed
Row, its bus is passed through after current transformer center hole, then install Up Highway UHW, busbar.This traditional approach not only influences user
Normal electricity consumption, and due to need dismounting bus, busbar, bring many uncontrollable factors, have dangerous hidden danger；Manpower,
Also bigger input is required in material resources.
Open Type Electric Current Mutual Inductor can open transformer magnetic circuit when mounted, bus, busbar are passed through transformer punching
Magnetic circuit is closed again behind hole, can need not so change existing distribution line, it is to avoid have a power failure, dismounting bus, busbar the problem of,
And human and material resources are saved, increasingly it is widely applied.Can be due to folding fit current transformer be cut open due to magnetic circuit,
General iron core is directly exposed in air, and when for outdoor or indoor moisture environment, core section, which easily makes moist, to get rusty,
Transformer transduced precision is caused to be deteriorated, bad stability, or even cisco unity malfunction, it is badly in need of wanting water proof type folding Current Mutual Inductance
Device.
Water proof type Open Type Electric Current Mutual Inductor on current market, structure is relatively easy.It is to use epoxy encapsulation material
Or other encapsulating compounds are firmly cast in iron core and winding in two parts shell of transformer, in exposed core section periphery
Increase ring structure on housing, then tightened respectively with two bolts on the outside of iron core incision, transformer housing, fastening is mutual
Sensor two parts and press the sealing ring at composition surface to seal iron core joint, prevent that water or air from invading core section,
So as to prevent from getting rusty.But this structure due to two parts iron core and correspondence shell be relatively fixed, can not within the specific limits freely
It is mobile, the tightness on two iron core composition surfaces be limited by near fastening bolt or other fastening structures, it is impossible to ensure consistent so that
Preventing transformer, deterioration in accuracy, uniformity are not in place from being guaranteed, or even due to fastening after tightening, cause product can not be just
Often work.And due to being fastened using bolt, if bolt fastening can not also ensure the effect of sealing structure when not in place, it is impossible to reach
To the purpose of waterproof.Due to the inherent shortcoming of its structure, current water proof type Open Type Electric Current Mutual Inductor does not obtain more extensively should
With.
