Description
Technical field
The present invention relates to the power system insulation bus, relate in particular to the single-ended shielding capacitor type insulating bus of above each electric pressure of a kind of electric power system 6kV.
Background technology
At present, when the terminal of the transmission line that constitutes with the high voltage capacitive-type isolated bus is connected with overhead wire, need final stage capacitor type insulating bus one end can shield connection, the other end can be realized built on stilts the connection, 6kV～35kV capacitor type insulating bus realizes that shielding connects the two kinds of schemes that adopt now: the one, and the field fabrication capacitor type insulating, the 2nd, install shielding cylinder additional.And take above two schemes to realize that two sections high voltage capacitive-type isolated buses shieldings connect, there are complex process, security reliability is low, cost is high problem.
Summary of the invention
Shield the connection aspect and have complex process in order to overcome present stage high voltage capacitive-type isolated bus, security reliability is low, the problem that cost of manufacture is high, and solve the problem be connected with overhead wire simultaneously, the present invention proposes a kind of single-ended shielding capacitor type insulating bus, one end adopts the plug in construction other end to adopt connection terminal structure and full skirt is set, the single-ended shielding capacitor type insulating bus that adopts the present invention to propose, do not need independent insulation shielding formula intermediate connector, simple in structure, cost of manufacture is low, easy construction, omnidistance insulation shielding, can detect in factory, baffle is connected to plug-in type, can realize that bus expands with heat and contract with cold freely to adjust, and does not also need to use independent outlet sleeve pipe at the overhead wire link in addition again.
The technical solution adopted for the present invention to solve the technical problems is, single-ended shielding capacitor type insulating bus mainly comprises baffle, the rigid insulation tube, mounting flange, the capacitor type insulating body, it is characterized in that: the end that baffle is arranged on center and baffle is provided with the grafting termination of band inserting groove and the other end is provided with binding post, the grafting termination of baffle and a rigid insulation tube are connected and fixed, another termination of rigid insulation tube is fixed on the mounting flange, outside at rigid insulation tube and baffle packs the capacitor type insulating body with the organic insulation band, the interior screen of the capacitance plate of described capacitor type insulating body and baffle equipotential and outermost screen is by the mounting flange reliable ground, and the capacitance plate of described capacitor type insulating body is ladder difference shape from inside to outside in a side that is positioned at the inserted terminal head and progressively extends and be ladder difference shape from inside to outside in a side that is positioned at binding post and progressively shorten, the capacitor type insulating body also is provided with rigid seal and also is provided with grading ring in the rigid seal outside on the termination that is positioned at binding post one side, also be provided with oversheath and be positioned at binding post one side in the oversheath outside in the capacitor type insulating external body also to be provided with full skirt;
Preferably, between the grafting termination of described baffle and the baffle and between binding post and the baffle be by be connected and fixed constitute one and described be connected comprise welding, be threaded, swelling connection or other known connection; Or described grafting termination, baffle and binding post are integral types;
Preferably, described baffle, grafting termination, rigid insulation tube external diameter are identical.
Beneficial effect, the single-ended shielding capacitor type insulating bus that the present invention proposes, following advantage is arranged: do not need independent insulation shielding formula intermediate connector, cost is low, installs simply, can vertically install; Behind the flange reliable ground, except having the voltage-transition district at built on stilts link, the bus outer surface all is an earth potential, and phase fault is avoided in omnidistance shielding, can make alternate bus close, and safety also is convenient to fix; The whole manufacturing finished in factory, and can detect separately; Baffle is connected to grafting, can realize that bus expands with heat and contract with cold freely to adjust; No longer need independent appearance sleeve pipe at the overhead wire link.
