When early stage China subway and light rail are built, 1500V direct-current isolating switch takes the mode of unit non-packed always, in recent years in order to make isolating switch from the impact of external environment, improve degree of protection, domestic new subway and light rail project include switch cubicle in design specification.Switch cubicle has easy for installation, takes up an area the features such as space is little, and degree of protection is high, and the life-span is long, is more and more subject to the favor of user.
According to the design specification of track traffic switch cubicle, the cabinet size of direct current isolating switch cabinet must not be greater than 800mm × 1000mm × 2200mm (wide × dark × high), cause in 1500V isolating switch cabinet design in the past, for cabinet, adopt isolating switch volume in the cabinet of vertical unfolding mode excessive, cause space in cabinet narrower and small, layout is tightly urged, wiring difficulty, the problems such as attended operation is inconvenient, especially at isolating switch gate-dividing state, be difficult to ensure to there is effective air insulation clearance between isolating switch and cabinet.
Summary of the invention
For deficiency structural in prior art, direct current 1500V isolating switch in the cabinet that the object of the invention is to design a kind of miniaturization, not only to meet the specification requirements of isolating switch, and space layout in cabinet will be optimized, solve layout tightly short, maintenance inconvenience, the problems such as divide-shut brake resistance is large.
For achieving the above object, the technical solution adopted in the utility model is to provide direct current 1500V isolating switch in a kind of cabinet, this isolating switch is arranged in subway DC isolating switch cabinet, wherein: this isolating switch includes switch pedestal, post insulator, revolution insulator, quiet disconnecting link assembly, moving knife gate assembly and arc-extinction device; Described moving knife gate assembly is arranged on revolution insulator, be positioned at the middle part of switch pedestal, two quiet disconnecting link assemblies are arranged on two post insulators respectively, be positioned at the two ends of switch pedestal, moving knife gate assembly and two quiet disconnecting link assemblies are in horizontal, linear contact lay between dynamic/static contact, two arc-extinction devices are arranged on dynamic/static contact respectively; When moving knife gate assembly 90-degree rotation, then disconnecting link assembly quiet with two is mutually vertical, forms disconnecting link double-fracture, the fracture insulation distance that double-fracture is remained valid.
Effect of the present utility model be this structure cabinet in 1500V isolating switch be used in track traffic subway direct-current switch cabinet, the beneficial effect of generation is:
1, in this cabinet, 1500V isolating switch structure is simple, easy for installation, maintenance-free.Can greatly reduce field service workload, reduce operation procedure, contact pressure is constant, without the need to adjustment, raises the efficiency and reduces system operation cost;
2, in this cabinet, 1500V isolating switch deciliter principles and structure is fairly simple, and conducting resistance is little, and lock resistance is little, and action is smooth and easy, and extinguishing arc action is fast, the life-span is long, the kind of drive is simple and convenient;
3,1500V isolating switch Miniaturization Design in this cabinet, volume is little, lightweight, greatly reduces production cost;
4, in this cabinet, 1500V isolating switch efficiently solves space layout in isolating switch cabinet and tightly urgees, and safeguards the problems such as inconvenient.No matter isolating switch is in which kind of state (separating brake or combined floodgate), separating brake double-fracture safety is complete to be leaned on and configures arc-extinction device, can and cabinet between ensure effective air insulation clearance, and can in an unloaded situation accurately deciliter and commutation circuit.

Embodiment
By reference to the accompanying drawings direct current 1500V isolating switch structure in cabinet of the present utility model is illustrated.
In cabinet of the present utility model, direct current 1500V isolating switch design philosophy is the Model Design adopting three pillar type to horizontally rotate isolating switch, two post insulators and one turn round insulator and are arranged on layout type on base side by side, a quiet disconnecting link assembly is arranged at the top of the post insulator of both sides respectively, top layout moving knife gate assembly of middle revolution insulator, and each installation arc-extinction device on two quiet disconnecting link assemblies, achieve the function of separating brake double-fracture and direct current arc extinguishing, fabulous solves the isolating switch separating brake difficult problem that volume is excessive later.
As Fig. 1, shown in Fig. 2, in cabinet of the present utility model, direct current 1500V isolating switch structure is, this isolating switch is arranged in subway DC isolating switch cabinet, and this isolating switch includes switch pedestal 1, post insulator 2, revolution insulator 3, quiet disconnecting link assembly 4, moving knife gate assembly 5 and arc-extinction device 6; Described moving knife gate assembly 5 is arranged on revolution insulator 3, be positioned at the middle part of switch pedestal 1, two quiet disconnecting link assemblies 4 are arranged on two post insulators 2 respectively, be positioned at the two ends of switch pedestal 1, moving knife gate assembly 5 and two quiet disconnecting link assemblies 4 are in horizontal, linear contact lay between dynamic/static contact, two arc-extinction devices 6 are arranged on dynamic/static contact respectively; When moving knife gate assembly 5 90-degree rotation, then disconnecting link assembly 4 quiet with two is mutually vertical, forms disconnecting link double-fracture, the fracture insulation distance that double-fracture is remained valid.
In cabinet of the present utility model, the function of direct current 1500V isolating switch is achieved in that
This isolating switch includes switch pedestal 1, post insulator 2, revolution insulator 3, quiet disconnecting link assembly 4, moving knife gate assembly 5 and arc-extinction device 6.In this cabinet, direct current 1500V isolating switch belongs to three pillar type and horizontally rotates isolating switch, with vertical opening type isolating switch comparatively speaking, during separating brake, moving knife lock does not take upper space, and moving knife lock is symmetrical to the left and right sides to launch.Two post insulators 2 are individually fixed in the two ends of switch pedestal 1, and a revolution insulator 3 is installed on the centre of switch pedestal 1, and post insulator 2 and revolution insulator 3 linearly mode are arranged, composition insulated part.Two quiet disconnecting link assemblies 4 are arranged on the top of two post insulators 2 respectively, and a moving knife gate assembly 5 is arranged on the top of revolution insulator 3, and quiet disconnecting link assembly 4 and moving knife gate assembly 5 are arranged in horizontal mode, composition current-carrying part.Again because direct current not zero crossing, arc extinguishing is comparatively difficult, so specially installed arc-extinction device 6 on dynamic/static contact, to eliminate electric arc more smoothly, proterctive equipment, is conducive to the safe operation of electrical network.
As shown in Fig. 3-1,3-2, post insulator 2 and quiet disconnecting link assembly 4 maintain static, revolution insulator 3 and moving knife gate assembly 5 synchronization action, when turning round insulator 3 and being rotated counterclockwise 90 degree, isolating switch closes a floodgate, two quiet disconnecting link assemblies 4 are closed into straight line, linear contact lay between dynamic/static contact, turning circuit completely with moving knife gate assembly 5; When turning round insulator 3 dextrorotation and turning 90 degrees, isolating switch separating brake, two quiet disconnecting link assemblies 4 are mutually vertical with moving knife gate assembly 5, define the two isolation fracture of clear eye-catching level, cut off circuit.
