Description

A kind of current transformer of nylon insulation

Technical field

The utility model relates to a kind of current transformers.

Background technique

In the prior art, current transformer generally carries out insulation processing by epoxide resin material, but due to epoxy resin There is carcinogenicity, and be difficult to degrade, after current transformer scraps discarding, would seriously pollute the environment and be detrimental to health, thus The method that epoxide resin material can be replaced to realize current transformer insulation need to be found out.

Summary of the invention

For overcome the deficiencies in the prior art, the utility model provides one kind and replaces epoxide resin material by nylon material The current transformer to insulate.

The technical scheme adopted by the utility model to solve the technical problem is as follows:

A kind of current transformer of nylon insulation, including for fixing mutual inductor bottom plate, be mounted on the bottom plate Current mutual inductor coil and a power connecting column being electrically connected with external realization, the current mutual inductor coil outer seal sleeve are equipped with Thermal insulation layer, mutual inductor outside form nylon inclusion enclave by injection molding nylon and wrap up current mutual inductor coil and mutual inductor route in fact It now insulate, a power connecting column exposes nylon and wraps up body surface face.

The current mutual inductor coil is installed by bracket, the bracket include the supporting clapboard that extends out from bottom plate and The suit column of the partition two sides, the current mutual inductor coil are separately mounted on the suit column of partition two sides for two, and Nylon insulating layer is folded between current mutual inductor coil and suit column.

The suit column is equipped with via hole, and the via hole, which is worn, is connected to energization column, and energization column is arranged in a power connecting column Both ends are equipped with nylon insulating layer between the energization column and via hole.

The nylon package is equipped with the secondary connection group drawn from mutual inductor route in vitro.

The beneficial effects of the utility model are: the mutual inductor of the utility model is by forming nylon bag in outside casting nylon It wraps up in body and realizes current mutual inductor coil, a power connecting column and mutual inductor route package and insulate, nylon inclusion enclave good insulation preformance, Easy to process and heated stress is unlikely to deform, can effectively instead of internal element of the epoxy resin to current transformer insulate every From the harmfulness and pollution problem that solution epoxy resin is brought；On the other hand, current mutual inductor coil sealing shroud is equipped with thermal insulation layer High temperature when nylon inclusion enclave melt molding can be effectively obstructed, is avoided when injection molding nylon since temperature is greater than holding for mutual inductor coil Caused coil to damage by boundary, influences properties of product.

Detailed description of the invention

The present invention will be further described with reference to the accompanying drawings and examples.

Specific embodiment

Referring to figs. 1 to a kind of current transformer of nylon insulation of Fig. 3, including the bottom plate 1 for fixing mutual inductor, installation Current mutual inductor coil 2 on the bottom plate 1 and a power connecting column 6 being electrically connected with external realization, current transformer line 2 outer seal sleeves are enclosed equipped with thermal insulation layer 3, mutual inductor outside forms nylon inclusion enclave 7 for current mutual inductor coil 2 by injection molding nylon And mutual inductor route package realizes insulation, a power connecting column 6 exposes 7 surface of nylon inclusion enclave, and nylon material has insulation performance The advantages that good, easy to process and heated stress is unlikely to deform effectively can replace epoxy resin to the internal element of current transformer It is dielectrically separated from, solves harmfulness and pollution problem that epoxy resin is brought；In addition, since nylon fusing point is higher than the paint of coil Envelope curve, can damage mutual inductor coil in injection molding influences the performance of product, therefore, is arranged outside current mutual inductor coil 2 heat-insulated Layer can effectively stop high temperature when 7 melt molding of nylon inclusion enclave is isolated, and coil is effectively protected in injection molding nylon and is not broken It is bad.

Referring to Fig. 4, as a preferred embodiment of the present invention, current mutual inductor coil 2 is installed by bracket 4, and bracket 4 wraps The suit column 42 of 41 two sides of the supporting clapboard 41 extended from bottom plate 1 and partition is included, current mutual inductor coil 2 is two and difference It is mounted on the suit column 42 of 41 two sides of partition, structure is simple and easy for installation, and above-mentioned suit column 42 is additionally provided with via hole 43, via hole 43 wear and are connected to energization column 61, and a power connecting column 6 is arranged in the both ends of energization column 61 and is pierced by nylon inclusion enclave 7 and external electrical connections Electrical circuit is constituted, current mutual inductor coil 2 is made to work；Current mutual inductor coil 2 and suit column 42 and energization column 61 and via hole It is folded with nylon insulating layer 5 between 43, nylon material is applied to the portion being dielectrically separated from needed for all current transformers On part.

Preferably, nylon inclusion enclave 7 be externally provided with from mutual inductor route draw secondary connection group 8, user can directly from It is external to be carried out by the connection electrical connection current transformer of secondary connection group 8 using convenient and efficient.
