Abstract

The electric circuit breaker pressurizing device is used for filling with dry gas chambers of breakers with two elements (1, 2) as shown in figure 1. each element has a base plae (3, 4) mounted on a common chassis (5) of the breaker. Each base plate (3, 4) has a non-return gas valve (6, 7) and each valve is connected by a pressure-tight connector (8, 9) and a length of tubing (11, 12) to a valve body (26, 27). Each valve body (26, 2me has a non-return gas valve (13, 14). the valve bodies (26, 27) are connected to a common junction block (25) which has a stirrup (37) for opening the valve by compressing the valve springs (15, 16) by turning a screw (33). the junction block (25) has a gas entry orifice (30) and a pressure gauge orifice.
