Abstract
The utility model relates to the technical field of plateau type high voltage breaker production, in particular to a plateau type comprehensive instrument transformer. A poured body is poured by epoxy resin, a voltage transformer and a current transformer are arranged in the poured body, high voltage signal output ends are arranged outside the voltage transformer and the current transformer, high voltage signal input ends are arranged at the top of the poured body, and an inner creepage wainscot and an outer creepage wainscot are arranged at the periphery of the poured body. Compared with a traditional comprehensive instrument transformer, the plateau type comprehensive instrument transformer structurally enables the current transformer and the voltage transformer to be integrated, and the wainscots are arranged on the inner wall to increase inner creepage distance. In operation, the plateau type comprehensive instrument transformer can accurately convert actual current and voltage values of a primary line into secondary small current and voltage without interfering each other to facilitate measurement and use. Thus, under the situation without changing functions, the plateau type comprehensive instrument transformer is simple and attractive in integral structure, convenient to install and capable of saving installation cost.
Description
Technical field:
The utility model relates to plateau type primary cut-out production technical field.
Technical background:
The instrument transformer that is applied at present on primary cut-out has the voltage transformer summation current transformer, and is separate, and voltage transformer and Current Mutual Inductance receiver and circuit breaker are used in conjunction with and are external hanging type, and volume is large, and wiring is loaded down with trivial details, expends mounting cost.
The utility model content:
In view of this, the technical problems to be solved in the utility model is to provide a kind of convenient comprehensive instrument transformer of plateau type of installing.
The comprehensive instrument transformer of the utility model plateau type comprises pour mass and dado, and the voltage transformer summation current transformer is set in described pour mass, and voltage transformer summation current transformer outside is provided with the high-voltage signal output; The high-voltage signal input is arranged on the top of pour mass, and the pour mass periphery is provided with interior creepage dado and outer creepage dado.
The utility model advantage:
Compare with traditional comprehensive instrument transformer, the utility model is structurally with current transformer and voltage transformer, be cast in the pour mass that vacuum interrupter is installed by the outdoor epoxy sealing, inwall has increased dado, thereby the creepage distance that compares in having increased, can be more accurate during operation actual current on circuit and magnitude of voltage are changed little electric current and the voltage that turns to secondary, and non-interference in order to measure uses, and can adapt to the area of height above sea level more than 2000 meters fully and use.Like this under the constant prerequisite of function, loaded down with trivial details wiring in the time of can avoiding the comprehensive mutual inductor on site of external hanging type to install and makeing mistakes, overall structure is simply attractive in appearance, is more convenient for installing and saving installation cost.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is that the right side of Fig. 1 is to schematic diagram.
Embodiment
As shown in Figure 1 and Figure 2, the comprehensive instrument transformer of the utility model plateau type, pour mass 1 is formed by poured with epoxy resin, and at the interior voltage transformer summation current transformer 2 that arranges of described pour mass 1, voltage transformer summation current transformer 2 outsides are provided with high-voltage signal output 3; High-voltage signal input 4 is arranged on the top of pour mass 1, and pour mass 1 periphery is provided with interior creepage dado 5 and outer creepage dado 6.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection range of the present utility model.
