Detailed Description
Intelligent small lockage (outdoor ring net ark) take the reference of foreign advanced technology, install and debug 10KV switchgear, circuit breakers, load switch, current and voltage transformer, 10KV power PT, lockage FTU, RTU, communication control terminals (CCU), 10KV measurement and automatic meter reading, UPS power meter etc then put into a movable, sealing, moisture-proof stainless steel box, thus fulfilling the urban distribution network, a secondary system of integrated, assembly of modularization and shorten the construction period and greatly enhance the city grid operation reliability.
1. Environmental conditions
Intelligent small lockage (outdoor ring net ark) take the reference of foreign advanced technology, install and debug 10KV switchgear, circuit breakers, load switch, current and voltage transformer, 10KV power PT, lockage FTU, RTU, communication control terminals (CCU), 10KV measurement and automatic meter reading, UPS power meter etc then put into a movable, sealing, moisture-proof stainless steel box, thus fulfilling the urban distribution network, a secondary system of integrated, assembly of modularization and shorten the construction period and greatly enhance the city grid operation reliability.
2.Characteristics usage
(1) body materials using imported stainless steel plate, thickness no less than 2mm, strong corrosion resistance, Beautiful appearance, compact structure, decorate reasonable, can use more than 30 years.
(2) case body surface without fasteners, and has the special door lock structure, good anti-theft, Cabinet of protection grade to IP3X, outdoor running, good rainproof.
(3)air interlining type bilayer structure for box cover, and equipped with vents, airinlet at the botom of body, outlet at the top and hidden below eaves ; Form a top-down air convection, make the good insulation and ventilated effect.
(4) the casing switch for SF6 fully closed structure, without heater, no frost problem; flood control, touch-type and water-proof cable plugs ,with unit FTU need strongthen ventilation and heater.
(5) appearance color can be chosen based on user requirements for design, users can choose the color harmonious with surrounding environment.
(6) box adopts high elastic sealing strip seals, make the product dustproof and moistureproof, prevent frost. Doors equipped with special designed lock.
Once equipment selection of lockage。
SM6, XGN15-12, RM6, SIMOSEC and other load switchgear is the best choice for outdoor small lockage once equipment, company specialized maked load switch high-pressure module for small lockage brings more compact structure.
These devices have closed, disconnect, grounding three positions, and have a lock function which can effectively prevent such wrong operations as grounding and grounding close brake with electricity.
All these once equipments have reliable mechanical interlocking, only in the grounding position can open outlet room door plank, ensure safety of person and operation.
Obvious simulation busbar pic can reliably shows switch closed, disconnect and grounding position, with electrification display device.
All load switch equipment can be equipped with current, voltage transformer, UPS power and FTU etc,to satisfy automation and measurement requirements.
Conventional load switch high-pressure module include load switchgear type, load switch + fuse assorted ark type, isolating switch + fuse ark type, load switch + breaker ark type, etc.
