Problems solved by technology
[0002] In recent years, the power grid has developed rapidly, and a large number of fully enclosed switchgears have been put into use. When the switchgear is overhauled, it often involves the overhaul of the busbar. At this time, the busbar needs to be grounded to ensure the safety of the construction. Because the busbar does not have a special grounding device, it needs to be overhauled. Personnel open the sealing plate of the busbar room of the switchgear, and sometimes it is necessary to destroy the original insulating sleeve of the busbar to be barely grounded. This operation method reduces the grounding reliability and poor safety
In addition, the operation is difficult and time-consuming

Embodiment Construction
[0029] The present invention will be further described below in conjunction with specific drawings and embodiments.
[0030] The switchgear universal busbar grounding device proposed by the present invention, such as figure 1 As shown, it mainly includes two parts, one is a chuck mechanism, which is used to clamp the static contacts in the switch cabinet, and the chuck mechanism is provided with a ground wire lead-out end; The busbar in the switch cabinet can be grounded; the second is an operating sleeve lever mechanism, which is used to connect and operate the chuck mechanism to clamp the static contact, and operate the sleeve rod mechanism and the chuck A connection structure that is relatively stuck and fixed when rotating and is convenient for axial separation is provided between the mechanisms. The chuck mechanism mainly includes figure 1 Some parts on the left side of the center, the operating lever mechanism mainly includes figure 1 Some parts on the right.

The invention provides a general type bus grounding device for a switch cabinet. The general type bus grounding device comprises a chuck mechanism and an operating sleeve rod mechanism, wherein the chuck mechanism is used for clamping a stationary contact in the switch cabinet and provided with a ground wire leading-out end; the operating sleeve rod mechanism is used for being connected with the chuck mechanism and operating the chuck mechanism so that the stationary contact can be clamped by the chuck mechanism, and a connecting structure which is fixed in a relatively clamped mode during rotation and facilitates axial separation is arranged between the operating sleeve rod mechanism and the chuck mechanism. The chuck mechanism comprises a connector, a circumferential damping structure is arranged on the circumferential surface of the rear end of the connector and used for being matched with a damping sleeve in the operating sleeve rod mechanism, the circumferential surface of the rear end of the connector is provided with an outer hexagon head for damping, the front end of the damping sleeve is provided with an inner hexagon head for damping, and the outer hexagon head for damping is matched with the inner hexagon head for damping. Through the device, engineers ground a bus of the switch cabinet conveniently during maintenance, operation is simple, safety is good, and working hours are saved.
Description
technical field [0001] The invention relates to an electric device, in particular to a universal busbar grounding device for a switch cabinet. Background technique [0002] In recent years, the power grid has developed rapidly, and a large number of fully enclosed switchgears have been put into use. When the switchgear is overhauled, it often involves the overhaul of the busbar. At this time, the busbar needs to be grounded to ensure the safety of the construction. Because the busbar does not have a special grounding device, it needs to be overhauled. When personnel open the sealing plate of the busbar room of the switchgear, sometimes it is necessary to destroy the original insulating sleeve of the busbar to be barely grounded. This operation method has brought about a decrease in grounding reliability and poor safety. In addition, the operation is difficult and time-consuming. [0003] Accordingly, it is necessary to design a grounding device that can be quickly connected...
