Description
Technical field
The utility model relates to a kind of combined floodgate structure, and more particularly, it relates to a kind of combined floodgate structure of isolating switch grounding switch.
Background technology
High voltage isolator is device for switching important in power plant and transformer station's electrical system, need support the use with primary cut-out, its major function is: ensure High-Voltage Electrical Appliances and the safety of device when service work, play isolation voltage, can not with cut-out, drop into load current and cut-off short circuit current, only can be used for some handover operation not producing powerful electric arc.The grounding switch of high voltage isolator attaching, accesses earth mat by system by grounding contact, and whether its ground connection reliably will directly affect operating personnel's life security.
At present, the grounding switch of the high voltage isolator on market, adopts T-shaped moving contact to coordinate with arc spring lamination fixed contact and contacts, this grounding switch is when stopping power transmission operation, earthing is when separating brake, and jam appears in earthing moving contact and fixed contact, causes earthing can not draw away; Earthing is when closing a floodgate, and jam after earthing moving contact contacts with fixed contact, causes phenomenon not in place of closing a floodgate, and therefore forms great threat to overhaul of the equipments personnel personal safety, increases the security risk of electrical network simultaneously, have a strong impact on and stop power transmission.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is the combined floodgate structure of the isolating switch grounding switch providing a kind of no-float.
For achieving the above object, the utility model provides following technical scheme: a kind of combined floodgate structure of isolating switch grounding switch, wherein: comprise ground connection knife bar and fixed contact, described fixed contact comprises pipe clamp, connector, described pipe clamp is connected on connector, described pipe clamp is set to U-shaped, and described ground connection knife bar snaps in described pipe clamp.
By adopting technique scheme, described ground connection knife bar directly snaps in fixed contact, eliminates the design of T-shaped moving contact, the structure of ground connection knife bar is more simple, provides cost savings, and uses the fixing contact of pipe clamp, ground connection knife bar snaps in pipe clamp, has larger contact area, no-float.
The utility model is set to further: described pipe clamp opening part is set to arc-shaped side.
By adopting technique scheme, arranging of arc-shaped side can guide ground connection knife bar to snap in smoothly and accurately, and card-tight part bit width is less than the diameter of ground connection knife bar, ground connection knife bar, while arc-shaped side snaps in, can strut pipe clamp, makes ground connection knife bar enter clamping position, be fixedly clamped, simple to operate.
The utility model is set to further: described pipe clamp inwall is provided with the raised line that punching press is formed.
By adopting technique scheme, stamping production efficiency is high, easy to operate, and production cost is low, and the setting of raised line reduces the distance in the middle of pipe clamp, increases the clamping force to ground connection knife bar.
The utility model is set to further: described raised line is set to two on the inwall of side, and described raised line is symmetrical arranged at pipe clamp both sides inwall.
By adopting technique scheme, ground connection knife bar snaps in pipe clamp and contacts with four raised lines respectively, four contact point symmetric contact, and clamping is stablized, and prevents to slide and skew.
The utility model is set to further: described connector is provided with bolt connecting hole.
By adopting technique scheme, with bolts, structure is simple, and bolt standard component easily obtains, and cost is low, and bolt fastening structure is compact, stable connection.
The utility model is set to further: described connector is set to U-shaped.
By adopting technique scheme, saving material, having saved the cost of equipment, and had certain bending strength for U-shaped, the stress that being rigidly connected when avoiding clamping produces is concentrated and is caused damage to equipment, extends the useful life of equipment.
