Abstract

The utility model relates to an electronic plastic housing circuit breaker. An iron core (2) for acquiring electricity is sleeved on a power supply bus (1) of the circuit breaker. A Rogowski coil (3) is wound on the power supply bus (1). The Rogowski coil (3) comprises a frame (3.1) on which an enamel insulated wire (3.2) is spirally wound. A protective sleeve (3.3) is coated outside an enamel insulated wire layer which is formed after winding the enamel insulated wire (3.2). The electronic plastic housing circuit breaker provided by the utility model can obtain wider measurement range without volume increase.

Description

Electronic type plastics case circuit breaker

Technical field

The utility model relates to a kind of circuit breaker, especially relates to a kind of electronic type plastics case circuit breaker, belongs to electrical equipment technical field.

Background technology

At present, in electronic type plastics case circuit breaker, all adopt iron core as the important devices of obtaining electric energy and signal, therefore for the wider situation of measuring range, thereby could meeting, the volume that need to increase iron core measures requirement, thus, greatly increased the volume of circuit breaker, be unfavorable for its installation, use and promote.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of electronic type plastics case circuit breaker that can obtain in the situation that not increasing volume compared with Wide measuring range is provided.

The purpose of this utility model is achieved in that a kind of electronic type plastics case circuit breaker, is set with the iron core for power taking on the power supply buses of described circuit breaker, on described power supply buses, is wound with Luo-coil.

The utility model electronic type plastics case circuit breaker, described Luo-coil includes skeleton, and on described skeleton, spiral winding has enamelled wire, and the enamelled wire layer of the formation after described enamelled wire is wound around has wrapped protective sleeve outward.

The utility model electronic type plastics case circuit breaker, the material of described skeleton is metal.

The utility model electronic type plastics case circuit breaker, described enamelled wire is wound with one or more layers.

The utility model electronic type plastics case circuit breaker, the lead-out wire at described enamelled wire two ends is positioned at Huo Tong one end, two ends of Luo-coil.

Compared with prior art, the beneficial effects of the utility model are:

The utility model obtains electric energy and signal by iron core and Luo-coil respectively, therefore for the circuit breaker of large rule also without the circle footpath that increases iron core, only need to increase the winding number of turn of Luo-coil, greatly reduced its volume.

Accompanying drawing explanation

Fig. 1 is the structural representation of the utility model electronic type plastics case circuit breaker.

Fig. 2 is the structural representation of the Luo-coil of the utility model electronic type plastics case circuit breaker.

Wherein:

Power supply buses 1, iron core 2, Luo-coil 3;

Skeleton 3.1, enamelled wire 3.2, protective sleeve 3.3, lead-out wire 3.4.

Embodiment

Referring to Fig. 1, a kind of electronic type plastics case circuit breaker that the utility model relates to, is set with the iron core 2 for power taking on the power supply buses 1 of described circuit breaker, and on power supply buses 1, is wound with Luo-coil 3,

Referring to Fig. 2, described Luo-coil 3 includes skeleton 3.1, described skeleton 3.1 is metal material, described skeleton 3.1 also can be used copper core cable, aluminium cable line, copper cash, aluminum steel or alloy wire, on described skeleton 3.1, spiral winding has enamelled wire 3.2, described enamelled wire 3.2 is wound with one or more layers, when adopting multilayer mode, can under the prerequisite in circle footpath that does not increase Luo-coil, increase the coiling number of turn of enamelled wire, the enamelled wire layer of the formation after above-mentioned enamelled wire 3.2 is wound around has wrapped protective sleeve 3.3 outward, the lead-out wire 3.4 at described enamelled wire 3.2 two ends is positioned at Huo Tong one end, two ends (be illustrated as from same one end and draw) of Luo-coil 3, two kinds of lead-out modes can be applied under all kinds of environment Luo-coil 3 easily.

During use, by iron core 2, obtain the required electric energy of electronic type plastics case circuit breaker, by Luo-coil 3, obtain the required measuring-signal of electronic type plastics case circuit breaker.
