Abstract
The invention provides a protective cover and an isolation switch equipped with the same, and belongs to the technical field of parts of an electric switch apparatus. The protective cover comprises a cover body, a threading port and a first operating port, wherein the cover body is suitable for being mounted on the base of the isolation switch and used for covering at least one contact base which is mounted on the base and used for connecting an inlet wire or an outlet wire; the threading port is formed in the cover body or between the cover body and the base, and used for allowing the inlet wire or the outlet wire to pass through; and the first operating port is formed in the cover body and used for allowing an operating tool to pass through to connect the inlet wire or the outlet wire on the contact base or remove the connection between the inlet wire and the contact base or between the outlet wire and the contact base. The protective cover provided by the invention is mounted on the base of the isolation switch, so that the contact base connected with the inlet wire or the outlet wire can be covered; and the first operating port is formed in the protective cover, the inlet wire or the outlet wire on the contact base can be connected and contacted without detaching the protective cover, so that wire connecting and wire detaching steps of the isolation switch can be simplified.
Description
technical field [0001] The invention relates to the technical field of components of an electric switchgear, in particular to a protective cover and an isolating switch having the same. Background technique [0002] The fuse-type isolating switch is a current protector. Its working principle is: when the current in the circuit exceeds the set value for a certain period of time, the heat generated by the current will melt the melt inside the isolating switch, thereby disconnecting the circuit. . The fuse type isolating switch mainly plays the role of isolation or short circuit protection in the line. When the isolating switch is in the separated position, the insulation distance between the moving and static contacts reaches a certain standard, and it has an obvious disconnection mark. When it is in the closed position, it can withstand the normal circuit current and the abnormal condition current within a certain period of time. [0003] Chinese patent document CN105374591...
