Description
Technical Field
The utility model belongs to the technical field of electrical equipment, and particularly relates to a safety control type load isolating switch.
Background
The load isolating switch is a device which isolates a power failure part from a power supply part in a power system so as to overhaul the fault or power failure state of an isolating device and guarantee the operation safety, and is widely applied to various power distribution systems and automatic systems. Its operation process is that the user switches the gear through stirring the handle, however, the operating handle that prior art designed does not be equipped with locking mechanical system, is very easily twistd reverse after being collided by external force, it is too loaded down with trivial details to press down or locking mechanical system, needs specialized tool to fasten (like the bolt locking), leads to the lazy locking in of the staff in the actual operation, in case lead to shifting by unexpected colliding with, the maintainer of contact outage system is very easily taken place to electrocute danger, consequently, needs a new device to improve this type of defect.
SUMMERY OF THE UTILITY MODEL
In view of the above-mentioned deficiencies in the prior art, the present invention provides a safety control type load isolation switch, which is used for ensuring that the load isolation switch realizes a stable and firm isolation state.
The utility model is implemented by the following modes: a safety control type load isolating switch comprises a main body, a rotating shaft, a main handle, a plate spring, a secondary handle, a supporting rod and an insulating ball head. The main body is an electrical box packaged with a load isolating switch functional component, the rotating shaft penetrates through and is installed on a main body shell, the top end of the rotating shaft is fixedly provided with a transverse main handle, the middle section of the main handle is fixedly provided with a plate spring, the plate spring is an arc-shaped plate made of spring steel, the end of the plate spring is fixedly provided with a secondary handle in the arc tangential direction, meanwhile, the end of the plate spring is fixedly provided with a supporting rod in the vertical direction, the end of the supporting rod is provided with an insulating ball head made of an insulating material spheroid, and the insulating ball head supports against the main body shell.
Furthermore, the utility model also comprises two insulating sleeves, wherein one insulating sleeve is sleeved on each end of the main handle and the secondary handle.
Furthermore, the end of the plate spring is fixed on the angle steel of the middle section of the main handle.
Further, the fixing mode of the plate spring and the relevant contact part is welding.
Further, the insulating ball head is made of rubber.
The utility model utilizes the design structure of the plate spring, the abutting rod and the insulating ball head to ensure that the main handle of the isolating switch is in a fixed state after the gear is arranged, the rotation of the main handle is effectively limited by the friction force applied to the insulating ball head to abut against the main body shell by the plate spring, meanwhile, an operator only needs to hold the main handle and the secondary handle to twist the plate spring and suspend the insulating ball head in the air, and the gear can be switched randomly.
Drawings
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic diagram of the adjustment state of the present invention.
In the figure: 1-main body, 2-rotating shaft, 3-main handle, 3 a-angle steel, 4-plate spring, 5-secondary handle, 6-abutting rod, 7-insulating ball head and 8-insulating sleeve.
Detailed Description
The utility model is described in further detail below with reference to the drawings and examples.
As shown in fig. 1, a safety control type load isolating switch comprises a main body 1, a rotating shaft 2, a main handle 3, a plate spring 4, a secondary handle 5, a resisting rod 6, an insulating ball 7 and two insulating sleeves 8. The main body 1 is an electrical box packaged with a load isolating switch functional component, the rotating shaft 2 is installed on a shell of the main body 1 in a penetrating mode, the transverse main handle 3 is installed and fixed at the top end of the rotating shaft 2, the plate spring 4 is fixedly welded on an angle steel 3a in the middle section of the main handle 3, the plate spring 4 is an arc-shaped plate made of spring steel, the secondary handle 5 is fixedly welded on the end of the plate spring 4 in the arc tangential direction, the abutting rod 6 is fixedly welded on the end of the plate spring 4 in the vertical direction, the insulating ball 7 of a rubber material spheroid is installed on the end of the abutting rod 6, the insulating ball 7 abuts against the shell of the main body 1, and the insulating sleeves 8 are respectively sleeved on the ends of the main handle 3 and the secondary handle 5. In an initial state, a pretightening force applied to the shell of the main body 1 is provided for the insulation ball head 7 through the plate spring 4, and the tangential direction of the rotating shaft 2 is fixed by using the friction force between the insulation ball head 7 and the shell of the main body 1.
As shown in fig. 2, when a power system fails and an operator needs to perform isolation detection on a specific area by using the load isolation switch function of the main body 1, the operator holds the primary handle 3 and the secondary handle 5 with a single hand, and twists the fingers upwards to move the secondary handle 5 upwards, at this time, the leaf spring 4 is twisted, the resisting rod 6 and the insulating ball 7 are lifted, the operator can directly stir the two handles to rotate around the rotating shaft 2 as an axis, when the corresponding gear is switched to, the fingers originally pressing the secondary handle 5 are released, so that the leaf spring 4 rebounds, the resisting rod 6 and the insulating ball 7 are propped against the shell of the main body 1 again, the state shown in fig. 1 is returned (but the gear is switched to the isolation position), at this time, the operator can go directly to the isolation area for maintenance, the rubber surface of the insulating ball 7 is continuously pressed against the shell of the main body 1 by using the elastic force of the leaf spring 4, and the friction force of the main handle 3 is ensured not to be twisted by an external force, the safety of maintainers is guaranteed.
The above description is only one of the embodiments of the present invention, and is not intended to limit the scope of the present invention, and it should be noted that other modifications and substitutions by those skilled in the art may be made without departing from the scope of the present invention as set forth in the appended claims.
