Abstract
The utility model discloses a metal armored pulling-out switch device comprising a cabinet body equipped with a box door. A bus chamber and an instrument chamber are disposed at the upper part of the inner cavity of the cabinet body. The middle part of the inner cavity of the cabinet body is a breaker handcart chamber. The lower part of the inner cavity of the cabinet body is a cable chamber. Three phase buses are mounted in the bus chamber. A breaker and a current transformer are mounted in the breaker handcart chamber. A primary cable, a grounding switch, and a lightning arrester are mounted in the cable chamber. The primary cable is connected with the current transformer. The current transformer is connected with the bus through the breaker and a switch. A heater is disposed at the primary cable. The metal armored pulling-out switch device uses a handcart moving mechanism in order to increase the maintenance flexibility of devices and applies a valve mechanism in order to enhance the maintenance security of the devices.
