Abstract
The utility model provides a high-voltage metering box which comprises a box body, a current transformer arranged in the box body, a voltage transformer arranged in the box body, as well as sleeves arranged on the box body, wherein the sleeves include a transverse sleeve and a vertical sleeve; both the primary side incoming line of the current transformer and the primary side incoming line of thevoltage transformer are arranged by penetrating through the transverse sleeve; both the primary side outgoing line of the current transformer and the primary side outgoing line of voltage transformerare arranged by penetrating through the vertical sleeve; an aviation plug is arranged on the box body, and both the secondary lateral line of the current transformer and the secondary lateral line ofthe voltage transformer are arranged by penetrating through the aviation plug; the current transformer adopts a full-enclosed type current transformer, and the voltage transformer adopts a full-enclosed type voltage transformer; the box body adopts a sealing structure; and a rain cover is arranged at the outer end part of the sleeve. The high-voltage metering box has the advantages of unique design, good moisture resisting performance, low accident rate, long service life, convenient use and strong practicability.
Description
Technical field
The utility model relates to a kind of casing, specifically, has related to a kind of High-voltage measuring box.
Background technology
Existing High-voltage measuring box is able to a large amount of uses owing to it possesses good anti-stealing electricity function, but after using a period of time, especially use above 2 years, be prone to mutual inductor blast or burnout failure, by analysis, the High-voltage measuring box that uses mainly exists not enough in the following aspects now: 1, casing moisture preventive measure deficiency, and mutual inductor is exploded because of making moist, accidents caused; 2, mutual inductor is once into and out of the shared sleeve pipe of line, easily makes the adhesion of turnover line, causes metering inaccurate, and simultaneously, the sleeve pipe upper lid easily comes off, and equipment is made moist and causes the mutual inductor blast; 3, mutual inductor is type semienclosed, and insulating protection grade deficiency easily makes the mutual inductor discharge that it is burnt.
In order to solve the problem of above existence, people are seeking a kind of desirable technical solution always.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, thereby a kind of High-voltage measuring box ingenious, that humidity resistance good, accident rate is low, the life-span is long, practical that designs is provided.
To achieve these goals, the utility model provides a kind of High-voltage measuring box, comprise casing, be arranged on current transformer in the casing, be arranged on the voltage transformer (VT) in the casing and be arranged on sleeve pipe on the casing, described sleeve pipe comprises horizontal sleeve pipe and vertical sleeve pipe, the primary side inlet wire of described current transformer and described voltage transformer (VT) passes described horizontal sleeve pipe setting respectively, and described vertical sleeve pipe setting is passed in the primary side outlet of described current transformer and described voltage transformer (VT) respectively; Described casing is provided with aviation plug, and the secondary side line of described current transformer and described voltage transformer (VT) passes described aviation plug setting.
Based on above-mentioned, described current transformer is the full seal type current transformer, and described voltage transformer (VT) is the full seal type voltage transformer (VT).
Based on above-mentioned, described casing is the hermetically-sealed construction casing.
Based on above-mentioned, described sleeve pipe outer end is provided with rain cover.
The relative prior art of the utility model has substantive distinguishing features and progress, and specifically, this High-voltage measuring box has the following advantages:
1, casing adopts all-sealed structure, humidity resistance excellence;
2, once pass in and out line separately, from different sleeve pipe turnover, and vertical mutually, avoid adhesion;
3, mutual inductor is a Totally-enclosed-type, and the degree of protection height is difficult for ging wrong;
4, the user can select the primary connection mode as required, can select the V-V mode of connection also can select the Y-Y mode of connection;
5, secondary line is drawn by aviation plug, guarantees that the integral sealing effect and the technology of casing is attractive in appearance.
