Abstract
The utility model relate to a high-voltage switch cabinet comprising a main bus chamber, a breaker, a cable chamber, and three current transformers disposed in the cable chamber. The main bus chamber is equipped with three phases of inlet wire copper bars connected with the input end of the breaker chamber. The cable chamber is equipped with three phases of outlet wire copper bars connected with the output end of the breaker chamber. The three current transformers are connected with a corresponding outlet wire copper bar in an inductive manner, respectively. The high-voltage switch cabinet is characterized in that two adjacent current transformers are distributed in a staggered manner. By using the above technical scheme, the three current transformers are distributed on a horizontal plane or a vertical plane in a mutually staggered manner and are arranged in a shape of an equilateral triangle. Long enough distance among the current transformers is arranged. Therefore, electric discharge phenomena caused by over short distance among the current transformers can be completely prevented and the secure reliability of the high-voltage switch cabinet is substantially increased.
