Device, it may also be used for power to the isolated mini system such as offshore oil platform, island, future can be additionally used in city electric distribution system, access
Fuel cell, photovoltaic generation distributed power supply.
High voltage dc transmission technology is in current engineer application, mainly by two current conversion stations and DC transmission line group
Into.By taking the engineering of wine lake as an example, the valve field of whole engineering is made of 4 valve Rooms, and each valve Room includes six valve towers.Each valve tower point
Four layers of valve, every layer includes 4 thyristor components, and each thyristor component has 7~8 Thyristors.Whole engineering is wrapped altogether
Include Thyristor 4392.Therefore experimental stage in engineering and trial operation stage, due to the various objective originals such as testing, overhauling
, there is the problem of replacing Thyristor in cause.
And the main problem of live Thyristor dismounting is at present：Security is poor, operating difficulties.Reason mainly has four
Aspect：One：Valve tower is suspended on the valve Room, and whole replacement process belongs to working at height；Two：Since the distance between valve layer limits
System, causes whole operation process that narrow space can be used, is unfavorable for operation；Three：Since the Thyristor of same component is logical
Certain pressure is crossed to be press fit together, so when dismantling Thyristor, it is necessary to carry out pressure release, but can only be to failed thyristor
Element carries out pressure release, other elements must not be influenced, so just needing particular tool to complete this disassembly process.
Utility model content
The purpose of this utility model be to provide it is a kind of it is simple in structure, small, manufacture cost is low, easy to use and safety
The high two point run-in index provision for disengagement of property.
To achieve the above objectives, the utility model, which adopts the following technical scheme that, is achieved：
A kind of two point run-in index provision for disengagement, including oil path block, ultrathin hydraulic jack and nylon bracket；
Oil path block is connected to the first hydraulic oil pipe and the second hydraulic oil pipe of perpendicular setting by two close end, 2
Ultrathin hydraulic jack is separately fixed on the first hydraulic oil pipe and the second hydraulic oil pipe, and oil path block both ends are sealed with plug respectively
It is stifled, the quick coupling for being connected with external hydraulic pump is also equipped with oil path block, being used for when use is provided with oil path block will
The fixing bracket that provision for disengagement is connected with external device (ED)；
Pressure is applied to provision for disengagement by external hydraulic pump, makes a ultrathin hydraulic jack by failed thyristor element two
The radiator of side struts, to realize the dismounting of Thyristor, replace.
Further, accumulator, which is connected through a screw thread, is fixed on oil path block.
Further, oil path block is connected through a screw thread with the first hydraulic oil pipe and the second hydraulic oil pipe, 2 ultra-thin hydraulic jacks
Top is connected through a screw thread with the first hydraulic oil pipe and the second hydraulic oil pipe, and quick coupling, plug and oil path block are connected through a screw thread,
All threaded connection places are equipped with seal washer.
Further, the fixing bracket includes being stuck in nylon bracket on oil path block by card slot, nylon bracket and with pressing from both sides
Plate 0 and bolt are fixed on oil path block, and supporting rod passes through nylon bracket, for fixing provision for disengagement；
Further, in the via above the supporting rod insertion nylon bracket, it is flexibly connected with nylon bracket.
The kinds of point mode thyristor provision for disengagement of the utility model by oil path block, hydraulic oil pipe, ultrathin hydraulic jack and
Nylon bracket etc. forms.Whole device connects exterior oil pump by quick coupling, and hydraulic oil is reached by oil path block, connected pipes
Ultrathin hydraulic jack, so that the radiator of failed thyristor both sides is softened, then takes out failed thyristor.Utilize this dress
Put, 2 hydraulic jacks can be made to realize synchronization job, ensure both ends radiator uniform force；Using this device, realize only
Pressure release replacement is carried out to failed thyristor element, the purpose without influencing other Thyristors, solves in replacement process
Hidden danger of quality；This device volume is small, light-weight, it is only necessary to which 1 people can operate.
Further, to prevent pressure is excessive from damaging radiator, accumulator 9 is installed on oil path block 1, it is certain when reaching
During pressure, hydraulic oil just enters in accumulator, so as to fulfill the overload protection to whole device.When two side radiators are softened
Afterwards, from relatively low 3 side of hydraulic jack, failed thyristor is taken out, and the thyristor more renewed.Finally device is let out
Pressure, device is removed, and thyristor component is pressed again, completes whole dismounting, replacement process.
