Problems solved by technology

If there is a fault in the switch body, try sending it directly, because the safety distance will be insufficient, and the arc generated by the faulty switch will cause personal injury
2. Using a 10kV insulated operating rod to operate, although the on-site personnel can keep a certain safe distance from the 380V and below voltage class shell circuit breaker, but the 10kV insulated operating rod body and the 380V and below voltage class shell type circuit breaker are not compatible. Matching, easy to shift during operation, resulting in operation failure

Embodiment 1

[0019] Such as figure 1 with figure 2 As shown, an insulated operating rod for a shell type circuit breaker includes an operating rod 1. A concave operating joint 2 is provided at the top of the operating rod 1. When in use, the concave operating joint 2 is snapped into the shell The operating handle of the circuit breaker.

[0020] When in use, the recessed operating connector 2 is clamped into the operating handle of the case-type circuit breaker, and the shaft of the operating lever 1 is held by hand, and the recessed operating connector 2 is pressed against the operating handle of the case-type circuit breaker, and the shell-type The operating handle of the circuit breaker is lifted upwards to realize the disconnection operation.

[0021] In this embodiment, the width of the female operating joint 2 is 4.7 cm. According to statistical measurement, the width of the operating handle of the common 630A low-voltage shell circuit breaker is 3.8 cm, so the designed width of the co...

Embodiment 2

[0027] In order to adapt to different use environments, the concave operating joint 2 can be connected to the operating rod 1 through a universal head to realize multi-angle rotation and facilitate the operation of circuit breakers in complex environments.

Abstract

The invention relates to an operating rod, in particular to an insulation operating rod for a shell type circuit breaker. The operating rod comprises an operating rod body, the top end of the operating rod is provided with a concave operating joint, and when the operating rod is in use, the concave operating joint is clamped inside an operating handle of the shell type circuit breaker. The insulation operating rod can be applied to the operation of the shell type circuit breaker with voltage classes of common 380 volts and below in the market.

Description

Technical field [0001] The invention relates to an operating rod, in particular to an insulating operating rod used for a shell type circuit breaker. Background technique [0002] Operating a shell circuit breaker with a voltage level of 380V and below is a common troubleshooting task in power supply emergency repairs. But so far, there are no tools and instruments specifically designed to operate shell circuit breakers with voltage levels of 380V and below. At present, there are two ways to traditionally operate shell circuit breakers with voltage levels of 380V and below. 1. After wearing the protective equipment according to the regulations, wear insulating gloves and try the delivery directly. If there is a fault in the switch body, direct trial delivery will result in insufficient safety distance, and the arc generated by the faulty switch will cause personal injury. 2. Use the 10kV insulated operating rod to operate, although the site personnel can maintain a certain saf...
