Description
Technical field
The utility model relates to 10KV electric switch equipment, is applicable to the transmission & distribution electric field of intermediate voltage electric power system, i.e. a kind of solid insulated fully-closed switch equipment being provided with fusing combined electrical apparatus.
Background technology
Along with the progress of power equipment manufacturing process, more and more higher to the requirement of the electric supply installation of power equipment, need the safe and practical performance constantly improving power industry equipment.
Power equipment such as the ring main unit combined electrical apparatus of existing mesohigh domesticizes all, but domestic fusing combined electrical apparatus complex structure, volume are large, and cost is high.In existing ring main unit: fusing combined electrical apparatus has air insulation and SF6 gas-insulated two kinds, and air-insulated fusing combined electrical apparatus is obvious by environmental limitations, and in atmosphere exposed for a long time, security performance is not high; And the gas isolated fusing combined electrical apparatus of SF6, fuse and on-load switch are splits, without safety precautions, take up room large, complex structure, install and change all inconvenient.
Summary of the invention
In order to solve SF6 gas isolated fusing combined electrical apparatus switchgear complex structure, volume is large, the problem that cost is high, and the utility model provides a kind of solid insulated fully-closed switch equipment being provided with fusing combined electrical apparatus.
A solid insulated fully-closed switch equipment for fusing combined electrical apparatus is installed, comprises switch cabinet body, in described switch cabinet body, be provided with fuse unit body, striker mechanism and pole; The vacuum interrupter that described pole comprises isolator operating mechanism, load switch operation mechanism, isolation earthing switch, epoxy resin housing and is cast in epoxy resin housing; Described striker mechanism comprises striker mechanism claw and strutting piece; It is characterized in that, fuse unit body comprises fuse, outlet casing tube, fuse unit connecting plate, fuse unit base, ground connection cylinder and fuse unit; Outlet casing tube and ground connection cylinder are all arranged on the bottom of fuse, and fuse is arranged in fuse unit, and fuse unit is arranged on fuse unit base by fuse unit connecting plate, and striker mechanism is fixed on the nozzle of fuse unit by strutting piece.
When the electric current on fuse exceedes setting, fuse quick fuse, striker is made to beat on springboard, blocking lever contacts with the interlocking plectrum of on-load switch earthed switch integral operating mechanism simultaneously, on-load switch automatic brake separating, press earthed switch switch knob, earthed switch closes a floodgate, and completes the ground connection operation at the line two ends of fuse unit.
The utility model provides a kind of solid insulated fully-closed switch equipment being provided with fusing combined electrical apparatus, complicated to solve existing combined electrical apparatus scenario-frame, the problem that cost is high, fuse insulating barrel structure of the present utility model, it is designed with the shorting switch of leading-out terminal before and after fuse, and by three-station ground connection, linkage shorting switch closes a floodgate, carry out on-load switch combined floodgate again to realize, reliable ground is answered at the current limiting fuse two ends with making capability.
Fuse unit of the present utility model comprise have uncovered housing and cover described uncovered lid, housing is poured into a mould by APG forming technique used for epoxy resin and is formed, with the solid insulation housing of cavity, fuse is placed in the cavity of housing, vacuum interrupter ground connection, sealing is in described housing, from above scheme, the direct sealing of ground connection vacuum interrupter of the present utility model is in solid insulation housing, its insulation property are from the impact of external environment, adopt vacuum interrupter to carry out ground connection, make all to be in vacuum state during ground connection splitting or integrating, grounding safety is reliable.Have that structure is simple, function is complete, volume is little, reliability is high, low cost and other advantages.
