Detailed Description
The utility model is further described with reference to the following figures and examples.
As shown in fig. 1 to 5, a front view, a rear view, a left view, a right view and a perspective view of the low-voltage isolation switch with the state detection function of the utility model are respectively given, the low-voltage isolation switch is composed of a switch mounting plate 1, a switch static contact 2, a switch moving contact 3, a switch operating handle 4, a travel switch 6, a limit bracket 7 and a travel switch baffle plate 8, the switch mounting plate 1 plays a role of fixing and supporting, and is in a flat plate shape, and the number of the low-voltage isolation switches arranged on the switch mounting plate 1 is 1 or more than 1. A switch static contact 2 and a switch moving contact 3 of the low-voltage isolating switch are both fixed on a switch mounting plate 1, and the lower part of the switch moving contact 3 is hinged so as to rotate; and a switch operating handle 4 is fixed at the tail end of the switch moving contact 3.
In this way, the contact and separation of the switch moving contact 3 and the switch static contact 2 can be realized by shifting the switch operating handle 4, namely, the on and off (commonly called as closing and opening) of the low-voltage isolating switch is realized, and in order to realize the detection of the on and off states of the low-voltage isolating switch, a travel switch 6 is arranged on one side of the low-voltage isolating switch.
The travel switch 6 is shown fixed on the switch mounting plate 1 via the travel switch bracket 5, the travel switch 6 is provided with a rotating rod 9, and after the rotating rod 9 rotates at a certain angle, the state of the travel switch 6 changes (for example, the opening and closing point changes into the normal opening point). A travel switch baffle 8 is fixed on the switch operating handle 4, and a pulley 10 which is always contacted with the travel switch baffle 8 is fixed at the tail end of the rotating rod 9. Therefore, in the rotating process of the toggle switch operating handle 4, the travel switch baffle 8 also drives the rotating rod 9 to rotate, so that the state of the travel switch 6 is changed, and the detection of the on-off state of the low-voltage isolating switch is realized.
Therefore, the low-voltage isolating switch is internally provided with the travel switch 6 for detecting the on-off state (namely closing and opening) of the low-voltage isolating switch, and a device for detecting the state of the isolating switch does not need to be additionally designed, so that the size of an isolating switch assembly is reduced to a great extent, the cost of the isolating switch assembly is reduced, the operation is simple and convenient, the assembly is simple and easy, and the maintenance is convenient.
In order to ensure the safety when the low-voltage isolating switch is operated, a limiting bracket 7 is arranged on the outer side of the moving contact 3 of the switch, and the limiting bracket 7 is fixed on the switch mounting plate 1; in the process of rotating the switch moving contact 3, the switch moving contact 3 cannot excessively rotate due to the limiting effect of the limiting support 7 on the switch moving contact 3, and good safety is guaranteed when the low-voltage isolating switch is operated.
