Abstract
The utility model discloses an integral sealed terminal box, which adopts a thin plate integral welding structure and is installed on a motor stator clamping ring through bolts; a lead-out cable and an outgoing cable in the terminal box are connected together by welding, and an insulating treatment layer is arranged at the welding position of the lead-out cable and the outgoing cable by coating; the inner cavity of the terminal box is provided with a clamp, the lead-out cable is clamped in the clamp which is plugged by using a cushion block after the lead-out cable and the outgoing cable are welded and subjected with insulting treatment; in addition, the outgoing cable is fixed and sealed at an outgoing cable outlet of the terminal box by using glands; the protection grade of the glands reaches IP68; and the combined surface of the terminal box with the motor stator clamping ring is sealed by using a rubber gasket. The protection grade of the entire terminal box reaches IP 65 above.
Description
Technical field
The utility model relates to a kind of modular construction of motor, be a kind of integral seal junction box structure of motor specifically, this structure is used for the EMU traction electric machine, make little, in light weight, the withstand voltage height of traction electric machine terminal box volume, dustproof and waterproof preferably, and terminal box need not safeguard substantially, reduced motor cost and when safeguarding owing to safeguard the fault of improper generation; When the aging needs of outlet cable are changed, can easily change again.
Background technology
Along with the development of EMU, motor product has been proposed strict more requirement, require motor and the terminal box supporting with it HTHP and also be in the conductor fluid medium can be safe and reliable operation.And in existing technology, be used for motor to connect the terminal box of drawing power supply, its housing and loam cake adopt plain cast iron or injected plastics material to make usually, aging easily or seepage in the high temperature and high pressure flow body medium or in the high temperature and high pressure steam; Secondly, in the junction of housing and loam cake and housing and junction box seat of motor, and feed cable threading position, adopt common material and fitting method to seal, sealing is poor, particularly the wiring position is introduced or drawn to cable, because cable outer layer is the elastomeric material sheath, certain elasticity arranged, can shrink under the high pressure, aging easily in hot environment in addition, cause under the HTHP cable to introduce or draw sealing difficulty especially, sealing was easily lost efficacy.According to common traction electric machine terminal box design, terminal box inside lead and outlet cable adopt Bolt Connection or cable outlet are welded to the also head part of motor internal coil.The former requires motor that bigger space is arranged, the latter when the cable area is big the outlet difficulty and when cable is aging need disintegrate when needing to change motor with carry out insulation processing.Especially the limited space requirement terminal box volume of EMU is little, in light weight on the train; Traction electric machine develops to high voltage, high-power direction in addition, requires terminal box to have bigger creepage distance and bigger cable area to bear bigger electric current; Two contradictions seem more outstanding.Therefore need further to be improved.
Summary of the invention
The purpose of this utility model exactly in order to overcome the deficiency that existing junction box structure exists, proposes the better integral seal terminal box of dustproof and waterproof of little, in light weight, withstand voltage height of a kind of volume and energy.
In order to reach above-mentioned specification requirement, the junction box structure that the utility model adopts is: a kind of integral seal terminal box, terminal box adopt thin plate integral solder structure, and terminal box is installed on the motor stator trim ring by bolt; Terminal box inside lead and outlet cable be with being welded together, and scribble the insulation processing layer at the weld of lead-out wire and outlet cable.Be provided with a clamp at the terminal box inner chamber, lead-out wire is stuck in the clamp, and uses the cushion block jam-pack after lead-out wire and welding of outlet cable and insulation processing.In addition, in the outlet of the outlet cable of terminal box, the outlet cable is fixed and is sealed with screwing part; Screw the part degree of protection and reach IP68; Seal with rubber gasket between the faying face of terminal box and motor stator trim ring.Whole terminal box degree of protection reaches more than the IP65.
This structure has the following advantages: 1) terminal box adopts the thin plate integral solder, and is in light weight, preferably dustproof and waterproof; 2) terminal box is installed on the stator pressing ring with bolt, makes things convenient for the welding and the insulation processing of lead-out wire.Terminal box inside lead and outlet cable connect with welding, carry out insulation processing then.A clamp is arranged under the lead-out wire, have aspect the height, after lead-out wire welding and insulation processing, use the cushion block jam-pack with a certain distance from lead-out wire.The outlet cable is fixed and is sealed with screwing part, screws the part degree of protection and reaches IP68; Seal with rubber gasket below the terminal box.Whole terminal box degree of protection reaches more than the IP65.The utility model is a kind of integral seal junction box structure, has advantages such as little, in light weight, withstand voltage height of volume and dustproof and waterproof performance are good.
