Abstract

The invention discloses a fuse protector type disconnecting switch carried with a signaling device in a hanging mode. The fuse protector type disconnecting switch comprises a fuse protector type disconnecting switch body. The fuse protector type disconnecting switch body comprises a base, a handle and a fuse protector with an impactor. The back end of a handle is movably connected with the back end of the base, and the fuse protector is hung on the inner side face of the handle. The signaling device is further connected to the outside of one lateral plate at the front portion of the base, and an ejecting rod connected with the signaling device and arranged on a popup route of the impactor on the fuse protector is further arranged in the base. When the base is closed up through the handle, the signaling device is triggered to send a closing signal. When the fuse protector is fused, the impactor on the fuse protector triggers the ejecting rod to enable the signaling device to send a fusing signal. The fuse protector type disconnecting switch carried with the signaling device in the hanging mode can achieve connection and disconnection through the same signaling device and monitoring of an operation state of the fuse protector, so that the fuse protector type disconnecting switch body is simple in structure. The fuse protector type disconnecting switch can be combined into a double-pole disconnecting switch.

Description

technical field [0001] The invention relates to a low-voltage protective electrical appliance, in particular to a fuse-type isolating switch carrying a signal device. Background technique [0002] Fuse type isolating switch is a simple and effective protective device that is manually operated. It mainly plays the role of isolating circuit or short circuit protection in the line. The characteristic of the isolating switch is that when it is in the separated position, the insulation distance between the contacts reaches a certain standard, and it has an obvious disconnection mark, and it can withstand the normal circuit current and the abnormal condition current within a certain period of time when it is closed. The fuse type isolating switch is mainly composed of a base and a handle. The base is equipped with a socket, electric bolt, fuse indicator and switch indicator. The handle is connected to the base through a hinge shaft for rotation. A fuse is hung on the handle. The ...
