Detailed description of the invention
nullAs shown in Figure 1，This utility model one on-pole switch pull open after link grounding safety device，Including casing 1、On-pole switch 2、Disconnecting switch 3、Gangbar 4、Rotary shaft 5 and insulated tension pole 6，On-pole switch support 7 and disconnecting switch support 8 it is respectively arranged with on the upside of the two ends of described casing 1，Described on-pole switch 2 and disconnecting switch 3 are secured transverse on on-pole switch support 7 and disconnecting switch support 8 respectively，Described on-pole switch 2 is positioned at the mains side of casing 1，Described disconnecting switch 3 is positioned at the load side of casing 1，On described on-pole switch support 7 and disconnecting switch support 8, equal longitudinally-moving is provided with rotary shaft 5，Described on-pole switch 2 and disconnecting switch 3 are all connected with rotary shaft 5 by insulated tension pole 6，The upper end activity of the most described insulated tension pole 6 is correspondingly arranged in on-pole switch 2 and disconnecting switch 3，The lower end correspondence of described insulated tension pole 6 is fixedly installed in rotary shaft 5，It is hinged with gangbar 4 between two described rotary shafts 5，Make on-pole switch 2 and disconnecting switch 3 all the time one open、Another Guan Bi，Linked together by short-circuiting bar 9 between three static contacts of described disconnecting switch 3.
Being provided with co-acting lever 10 in described rotary shaft 5, described co-acting lever 10 is for folding on-pole switch 2 and disconnecting switch 3.
It is provided with back-moving spring 11 between lower end and on-pole switch support 7 and the disconnecting switch support 8 of described insulated tension pole 6.
This utility model can pass through short-circuiting bar 9 automatic earthing after on-pole switch 2 load side is pulled open, it is possible to reduce installs earth lead during power supply station's maintenance, guarantees safety simultaneously.
This utility model dependable performance, installs earth lead without maintainer after installation and gets final product work, works quick, safe and reliable.
This utility model casing 1 shell uses stainless steel material or the outdoor resin of general steel plate spraying UV resistant, has excellent corrosion resistance.External insulation uses silastic material, and insulation is reliable, and anti-filthy ability is strong, and fire-retardant SMC material and air composition compound inslation are selected in interior insulation, transless oil in casing, without sulfur hexafluoride gas, meets reforming without oil and environmental protection requirement.Clearly, simple, clear and definite identification phase sequence (yellow, green, red)；When disconnecting switch disconnects, ground connection linkage must have reliable grounded capacity, with should disconnecting switch close time also must reliable separation.
