Embodiment
A kind of magnetic suspension high pressure coupling box as shown in Figure 1, comprises casing 5, TKH11A isolation conversion switch 11, fuse 9, earth protective device 8, Waterproof connector of cable 3, three-core cable joint 6, a storehouse position socket 7.
As shown in Figure 1, described casing 5 is welded by angle steel between any two by six stainless steel faceplates.The detachable buckle 1 that is applied to the box house inspection and maintenance is bolted on casing 5 panels by 8 and adopts the sealing ring sealing.The panel assembly welding is equipped with the outlet that 7 Waterproof connector of cables 3 are used in the casing.The TKH11A isolation conversion switch is installed on casing 5 rear boards by 4 bolts, and the storehouse is bolted on the cabinet rear panel by 4 with position socket 7, is used for the connection that power supply is used in the storehouse.Earth protective device is installed on the casing lower panel by three bolts.4 mounting blocks are welded on respectively and are used for fixedly fuse apparatus on the upper and lower panel.4 circular holes of casing by suspension plate are installed at the bottom of the car.
As shown in Figure 4, described magnetic suspension is installed in the casing 5 with TKH11A isolation conversion switch 11 levels, is fixed on the coupling box rear board by the top panel perforate.The TKH11A isolation conversion switch is by manual operation, joystick is spacing by position-limiting drum, usually isolation conversion switch is limited in " normally " position or " storehouse is used " position, only has after the up lifting of joystick lever head, lifting restrictions, and joystick could switch the vehicle operation state.The handle installation shaft is fastening by the axle in sunk screw and the rotary drum assembling, and when joystick rotated, band fixed handle installation shaft was rotated with the rotary drum assembling, and wherein public fingertip contacts with contact all the time, guarantees that the output in two loops is connected.After normal position fingertip and contact broke away from, corresponding normal operating conditions loop disconnected, until the storehouse contacts with contact with the position fingertip, the storehouse is connected with the position operating state.Thereby realize the change over switch state switching performance.When rotary drum assembling rotation, axle drives the cam action that is mounted thereon, and control rack-mount auxiliary interlock apparatus switch pass and close, thus the signal feedback of realization change over switch operating state.
As shown in Figure 4, described fuse 9 is fixed on the mounting panel by its mount pad.When levitation train was in " normally " position operating state, by busbar 10 access pantagraph current collector (DC 1500V+) loops, vehicle was powered by pantagraph current collector.DTR-GL3 dc fuse 9, rated voltage 2000V, rated current 600A, fusible core rated current 400A.The high pressure coupling box adopts the fuse of three these models to be connected in parallel, and rated blowing-current can reach 1200A, satisfies the specification requirement of circuit rated current 1000A, realizes pantagraph current collector direct current main power feed loop is played the effect of short-circuit protection.
Described levitation train is mainly formed by protection diode, resistance, Capacitance parallel connection with high pressure coupling box earth protective device 8.Earth protective device 8 one ends connect the ground connection position of other equipment, and the other end is connected to casing 5 by the grounding nut on the casing.
As illustrated in fig. 1 and 2, described cable joint is installed on the cabinet panel, and one of them three-core cable joint 6 is used for connecting the feedback signal cable, all the other six Waterproof connector of cables, 3 link circuit cables.
Thus, levitation train high pressure coupling box is installed on the levitation train bottom, for satisfying the requirement of IP54 degree of protection, taked new protection Design: isolation conversion switch TKH11A panel and high pressure coupling box are installed the surface by the panel fluting, the sealing of fitting tight circle.Change axle sleeve fit system between axle and panel hole, the axle sleeve fluting, the fitting tight circle guarantees sealing.Handle outside 6mm cover plate is adjusted into protective cover, and Handle axis and spring no longer expose in air.
Because the whole lightweight requirements of levitation train, high pressure coupling box bulk is restricted.On the basis that considers size and function, the mechanism of box house has been carried out rational layout, simultaneously isolation conversion switch associated components size is adjusted with overall dimensions.Square shaft changes to 18 * 18 square shafts, and contact assembling overall length changes to 190mm, and contact assembling diameter changes to 92mm.Overall dimension changes to 348mm * 290mm.
Switch to " normally " position from " storehouse with " position: when the TKH11A isolation conversion switch was in " storehouse with " position state, the storehouse was with power supply current supply circuit closure.Under off-position, with the joystick lever head up lifting turn an angle to remove mechanical constraint, the storehouse disconnects with the position circuit, to approximately switching to " normally " after 63 °, puts down handle head, joystick is limited in " normally ".
Switch to " storehouse with " position from " normally " position: when the TKH11A isolation conversion switch is in " normally " state, pantagraph current collector current supply circuit closure.Under off-position, with the joystick lever head up lifting switch to " storehouse with " position after rotating approximately 63 ° to remove mechanical constraint, the storehouse is closed with the power supply current supply circuit, pressure can keep the good contact performance between fingertip and contact, puts down handle head, and joystick is limited in " storehouse is used " position.
The content that above-described embodiment is illustrated should be understood to these embodiment and only is used for being illustrated more clearly in the utility model, and be not used in the restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present utility model.
