The precondition of equipment reliability service.From conventional equipment installation and operation, the gate line that is inserted on TFM plate of discovery or other
, repeatedly there is virtual connection or the phenomenon being ejected completely by TFM plate in wire, brings very big potential safety hazard to converter valve safe operation, and
Significant blackouts accident may be caused.
Content of the invention
It is an object of the invention to provide a kind of simple in construction, connect reliable extra-high voltage direct-current transmission converter valve TFM plate
Locking device.
For achieving the above object, the present invention is by the following technical solutions:
A kind of extra-high voltage direct-current transmission converter valve TFM plate locking device, including TFM guide groove, injects what TFM guide groove was fixed
TFM plate, TFM guide groove is provided with five needle interfaces, and the TFM contact pin on TFM plate and outer lead joint are by inserting five needle interfaces
In be attached, TFM guide groove both sides are provided with left cable locking part and right cable locking part for fixing outer lead joint,
Left cable locking part is installed together with the employing snap fit of right cable locking part.
Further, described left cable locking part being provided with draw-in groove, right cable locking part relevant position is provided with claw, right
Cable locking part offers the limit rib of the stopper slot accommodating outer lead joint and restriction outer lead joint location, left electricity
Cable locking member offers the limit rib of the stopper slot accommodating outer lead joint and restriction outer lead position, left cable lock equally
Tight part and right cable locking part pass through draw-in groove and claw fastens, and outer lead joint is fixed by stopper slot and limit rib.
Further, described left cable locking part and right cable locking part all use injection mo(u)lding.
Further, described left cable locking part and right cable locking part all use high insulating property flame retardant plastics to make.
Further, described left cable locking part and right cable locking part are provided with multiple draw-in groove cooperating and card
Pawl.
The present invention includes left cable locking part and right cable locking part two parts, the TFM plate lock being arranged on TFM guide groove both sides
The cooperation of tight device uses buckle-type design, does not use securing member, and installation effectiveness is high, it is ensured that outer lead joint and TFM contact pin
It is reliably connected, it is to avoid the phenomenon that virtual connection or terminal are ejected by TFM plate occurs, it is ensured that and insulated fasteners can be avoided to lose
Fall inside converter valve tower.
Further, TFM plate locking device uses and meets the flame retardant plastics that converter valve design requires and owner requires, can be effective
Reduce fire risk.
Further, simple in construction, the volume of TFM plate locking device are little, low cost of manufacture, fire resistance are good, and parts are adopted
By Shooting Technique, parts one-shot forming, with short production cycle, product quality is high.TFM plate locking device is according to being repeatedly used for
The TFM guide groove of engineering is designed, and can realize lossless installation, and be applicable to conventional engineering.

Detailed description of the invention
Below in conjunction with embodiment, the invention will be described in further detail.
As it is shown in figure 1, extra-high voltage direct-current transmission converter valve TFM plate locking device, including TFM guide groove 3, inject TFM and lead
The fixing TFM plate 1 of groove 3, TFM guide groove 3 is provided with five needle interfaces 7, and the TFM contact pin 2 on TFM plate 1 leads to outer lead joint 5
Crossing in insertion five needle interfaces 7 and being attached, TFM guide groove 3 both sides are provided with the left cable locking for fixing outer lead joint 5
Part 4 and right cable locking part 6, left cable locking part 4 uses snap fit to be installed together with right cable locking part 6.
As shown in Figures 2 and 3, left cable locking part 4 being provided with draw-in groove, right cable locking part 6 relevant position is provided with
Claw, offers in right cable locking part 6 and accommodates the stopper slot of outer lead joint 5 and limit outer lead joint 5 position
Limit rib, left cable locking part 4 offers stopper slot and restriction outer lead joint 5 equally that accommodate outer lead joint 5
The limit rib of position, left cable locking part 4 and right cable locking part 6 pass through draw-in groove and claw fastens, and outer lead joint 5 passes through
Stopper slot and limit rib are fixed.
As shown in Figure 4, first five needle interfaces 7 and TFM guide groove 3 are linked together by securing member, when TFM plate 1 injects
