Description
Technical field
The utility model relates to earth system used for high-speed railway, is specially a kind of contact system short circuit test earth system.
Background technology
In today that electrified railway train running speed improves day by day, high speed railway construction is just flourish, in the engineering construction of High-speed Passenger Dedicated Lines electric railway, more and more higher requirement is proposed to contact system construction safety quality problems, when breaking down, can find out fast and process contact system fault, caliberating device requires particularly important for the accurate judgement of trouble point.
Contact system short circuit test is for detecting tractive power supply system fender guard function and protection act program, the accuracy rate of checking contact system trouble point caliberating device, according to test result, instructs for transformer substation system adjustment and optimizes, and meeting later stage operating and maintenance requirements.
Existing contact system short circuit test test point ground connection auxiliary device generally adopts rail vehicle or circuit breaker to carry out ground connection; the auxiliary facilities such as easy damage OCS Messenger Wire, contact wire, positive feeder, protective wire, Zhan Qian unit gapless rail; and operating process is wasted time and energy, affect construction speed.
Summary of the invention
The utility model adopts rail vehicle to there is fragile auxiliary facility and waste time and energy and affect the problem of construction speed to solve existing earth system, provides a kind of contact system short circuit test earth system.
The utility model adopts following technical scheme to realize: contact system short circuit test earth system, comprises mobile grounding part and dead earth part; Mobile grounding part comprises insulating bar, insulating bar top is fixed with the aluminum alloy hook hung on contact system, aluminum alloy hook is connected with the connected grounding jumper in one end, the other end of grounding jumper connects wired nose, line nose be through be hooked in leg lower end under rail claw bolt on, claw bolt is screwed with the L shape pressing plate being pressed in inboard leg under rail, the claw bolt inside pressing plate is screwed with jam nut; Dead earth part comprises on four claw bolt I being hooked in leg lower end under two one steel rails, and on each claw bolt I all cover have the L shape pressure plates I being pressed in inboard leg under rail, claw bolt I inside pressure plates I all has jam nut I, be installed with in the cavity that four block pressur plate I and corresponding claw bolt I surround one with the grounding jumper I of line nasal contact.
When carrying out grounding lattice short circuit test, the electric current of contact system transfers to location of rail place through grounding jumper, line nose, and connect with grounding jumper I, current spread is diverted on two one steel rails, overcomes existing earth system and adopt rail vehicle to there is fragile auxiliary facility and waste time and energy and affect the problem of construction speed.
The utility model reasonable in design is reliable; solve short circuit test and easily damage the construction difficult problems such as OCS Messenger Wire, contact wire, positive feeder, protective wire, gapless rail; shorten test period; accelerate construction speed; time saving and energy saving, there is the advantage that structure is simple, easy to operate and with low cost simultaneously.
