Abstract
The utility model discloses a contactor box with a mutual-inductor belonging to the field of electrical equipment, in particular to an element of an on-off cabinet used under the high-voltage. The contactor box with a mutual-inductor comprises a box body, a wire-coiling drum and a wire-tailing drum, wherein wire-coiling contactors are arranged in the wire-coiling drum, and wire-tailing contactors are arranged in the wire-tailing drum. The outside of the wire-coiling drum and the wire-tailing drum is provided with sunray pleats, the outer side of the box is provided with a supporting board, and the mutual-inductor is fixed in the box. The high-voltage wire-coiling end and the high-voltage wire-tailing end are respectively connected to the wire-coiling contactors and the wire-tailing contactors, wire-tailing terminals are arranged on the outside of the box, and the low-voltage end of the mutual-inductor is in connection with the wire-tailing terminals. The mutual-inductor is arranged in the contactor box by the utility model, thereby eliminating the insulating distance between the mutual-inductor and the contactor box and the on-off cabinet, enabling the on-off cabinet to be miniaturized and integrated, and further saving a great deal of materials and reducing the products costs.
Description
Technical field
The utility model belongs to appliance field, particularly a kind of element of high-tension switch cabinet.
Background technology
In high-tension switch cabinet, contact box has the fade function of turnover line, is a kind of requisite part.After using contact box, the installation of circuit and maintenance are all very convenient.Simultaneously, current transformer also is a kind of electric device very commonly used, is used for measurement and relaying protection to electric current, electric energy.At present, contact box and instrument transformer all are installed separately.Because national standard all has certain requirement to the creepage distance and the space insulation distance of high-tension electricity device, thus contact box and instrument transformer existed when being installed separately defectives such as floor space is big, product cost height, and have some unsafe factors.
Summary of the invention
The purpose of this utility model is in order to overcome the problems referred to above, a kind of contact box that has instrument transformer with integral structure to be provided.
The purpose of this utility model can realize by following technical proposal: the contact box that originally has instrument transformer comprises box body and the columnar wire feeding tube and the output cylinder that are connected as a single entity with box body, be provided with the inlet wire contact in the wire feeding tube, be provided with the outlet contact in the output cylinder, the outside of wire feeding tube and output cylinder is provided with diffusing skirt, box body arranged outside supporting bracket, instrument transformer is set in the box body, the high pressure end of incoming cables of instrument transformer and high-voltage terminal end are connected on respectively on inlet wire contact and the outlet contact, the box body outside is provided with outlet terminal, and the low pressure leading-out terminal of instrument transformer is connected on the outlet terminal.
The above-mentioned box body outside also can be provided with diffusing skirt, to increase creepage distance.Above-mentioned wire feeding tube inboard or output cylinder inboard can be provided with diffusing skirt equally, play a part same.
The utility model has been eliminated the insulation distance between instrument transformer and contact box, switch cubicle because instrument transformer is arranged in the contact box, makes switch cubicle miniaturization, integrated, can save lot of materials and reduce the cost of product.Simultaneously, after instrument transformer and contact box are connected as a single entity, install very conveniently, safe in utilization, have high economic benefit and social benefit.
Description of drawings
Fig. 1 is the cross-sectional view of the contact box that has instrument transformer that provides of the utility model.
Fig. 2 is the vertical view of the contact box that has instrument transformer that provides of the utility model.
Embodiment
As shown in Figure 1, the contact box that has instrument transformer that present embodiment provided comprises box body 1, wire feeding tube 2, output cylinder 3, instrument transformer 6 and supporting bracket 7.Wherein box body 1, wire feeding tube 2, output cylinder 3 and supporting bracket 7 are connected as a single entity, and adopt epoxy resin to form around notes, have the good insulation performance performance.Instrument transformer 6 is positioned at box body 1.In the present embodiment, supporting bracket 7 has two, is equipped with installing hole 70 on the every supporting bracket 7.
As shown in Figure 1, except having the diffusing skirt 20,30, also be provided with the skirt 10,21 that looses in the outside of box body 1 and the inboard of wire feeding tube 2 at the wire feeding tube 2 and output cylinder 3 outsides.Like this, can prolong the creepage distance of product greatly, improve its security performance.
On the high pressure end of incoming cables and high-voltage terminal end that inlet wire contact 4 in wire feeding tube 2 and the output cylinder 3 and outlet contact 5 are connected on instrument transformer 6 respectively.As shown in Figure 2,8 of the outlet terminals of connection instrument transformer 6 low pressure leading-out terminals are positioned on the supporting bracket 7.In the present embodiment, outlet terminal 8 has four.
The installation site of the contact box that the utility model provides and the installation site of common contact box are basic identical.
