Abstract
The utility model relates to a voltage transformer used in a high-voltage power transmission system, in particular to a built-in voltage transformer which can be arranged in a high-voltage AC demarcation switch. The built-in voltage transformer comprises an iron core, a coil and an insulated casting body which is covered at the periphery of the iron core and the coil. The outer surface of the insulated casting body is provided with a right-angle structure which is formed by two mutually perpendicular positioning installing surfaces; positioning plates or positioning installing plates which areparallel to the positioning installing surfaces are connected at both sides of the positioning installing surfaces; the positioning plates or the positioning installing plates are fixedly arranged onthe positioning installing surfaces through screws; and the positioning installing plates are also provided with installing holes which are connected with the inner surface of a shell in the high-voltage AC demarcation switch. The built-in voltage transformer has simple structure, can be integrated in the high-voltage AC demarcation switch, and has convenient transportation and installation.
Description
Technical field
The utility model relates to a kind of voltage transformer that is used for high voltage power transmisson system, specifically is a kind of built-in voltage transformer that is installed in the high-voltage alternating demarcation switch.
Background technology
In the existing outdoor high voltage switchgear, high-voltage alternating boundary vacuum circuit-breaker and voltage transformer are fabricated to separately independently product usually respectively, support separately is installed and is carried out wiring respectively on the shaft tower out of doors when mounted, therefore exist following defective:
1, voltage transformer is external, makes packing and transportation occupy greater room, has increased packing and cost of transportation;
2, special voltage transformer support need be installed during outdoor installation, not only cost is higher, has also increased loaded down with trivial details installation procedure;
3, the external meeting of voltage transformer causes life of product to shorten because of reasons such as the external world is ultraviolet, aging, environmental pollution influence its electric property hugely.
4, external installation back mounting bracket of voltage transformer and connecting line increase, and have increased the potential safety hazard of high-voltage line protection and have influenced attractive in appearance.
Summary of the invention
Technical problem to be solved in the utility model is, provide a kind of volume little, simple in structure, can integratedly be installed in the high-voltage alternating demarcation switch, transportation and built-in voltage transformer easy for installation.
Built-in voltage transformer of the present utility model includes iron core, coil and is coated on iron core and the insulation pouring body of coil periphery, and the outer surface of described insulation pouring body has the right-angle structure that is made of two orthogonal location and installation faces; Be connected with location-plate equal or location and installation plate in location and installation face both sides with the location and installation face; Described location-plate or location and installation plate are installed on the location and installation face by screw; Also have on the described location and installation plate and be used for the installing hole that is connected with the box inside of high-voltage alternating demarcation circuit breaker.
Distinctive appearance structure of the present utility model can make in its casing that is installed in the high-voltage alternating demarcation switch easily, reduced the space hold of entire equipment, not only pack and convenient transportation, also saved special voltage transformer support has been set in the work progress, reduced cost, simplified construction; Simultaneously, the built-in voltage instrument transformer has been avoided loaded down with trivial details external cabling in the equipment construction process, has improved the operational reliability and the non-maintaining property of complete set of equipments, has prolonged its useful life.
