Description
Technical field
The present invention relates to binding post field, more particularly to a kind of connecting terminal apparatus with auxiliary connection protection.
Background technology
Secondary returning is generally realized with binding post inside the screen cabinet such as relay protection of power system screen, terminal box or central console
The switching and connection of road cable, for part terminal due to the needs of experiment, setting can stir bridge joint mechanism and wiring sleeve.Bridge joint
Mechanism is used for the metallic conductor at connection terminal both ends, including upper and lower connection sheet and stirs screw, can manual toggle bridge joint mechanism,
Realize that connecting terminal apparatus both ends are in " connection " or "off" two states；Screw is stirred then by upper and lower locked and fixed in flakes
In current state, connection or the effect disconnected are played.Experiment line jack and short circuit line jack are connected directly to terminal gold
Belong to piece, and internal diameter is slightly larger than the metal jack of test wire plug external diameter, easily and reliably inserts and pulls out temporarily during for testing
Go out test wire.It is additional sleeved in experiment line jack or short circuit line jack typically in order to fix the test wire plug of insertion, it is referred to as
For test cartridge or short circuit sleeve.The binding post at secondary circuit cable line both ends is typically by a bridge joint mechanism connection, bridge
Connection mechanism include it is upper in flakes, under in flakes and stir and whether connected between screw, that is, both ends cable, depend entirely on both ends
Binding post between bridge joint mechanism position and connection status.
In relay protection of power system, current loop particularly in differential relaying panel, in progress bus differential protection device or certainly
When throwing the periodic inspection debugging of device, it is necessary to carry out technical safety measures according to a graded, arrangement before debugging efforts and
" the working specification order " being had to comply with resuming work after the completion of debugging efforts.It is widely used in bus protection screen or standby
The above-mentioned testing terminal of routine on the similar devices such as screen is hauled oneself willingly into, the appearance of faulty operation can not be prevented in structure, it is female when carrying out
When line protection device or backup auto-activating device periodic inspection are tested, due to the personal specialized capability of staff and the spiritual shape on the same day
The reasons such as state, it is most likely that occur following " six kinds of mistake operations "：
1st, CT sides short circuit sleeve is not inserted into shorting stub and just directly stirs bridge joint mechanism to "off" state；
2nd, do not recover bridge joint mechanism to " connection " state and just directly remove shorting stub；
3rd, protection side joint line sleeve is inserted into shorting stub by mistake, stirs bridge joint mechanism afterwards to "off" state；
4th, test wire is inserted into CT side joint line sleeves by mistake, stirs bridge joint mechanism afterwards to "off" state；
5th, bridge joint mechanism is not allocated to "off" state and is just inserted directly into test wire；
6th, non-pull line and directly will bridge joint mechanism recover to " connection " state.
Any maloperation of the above 1 to 4, directly artificially causes CT second open circuits, and operating current transformer will be
The terminal connecting plate both ends of disconnection generate the high voltage of volts up to ten thousand, and breakdown insulation, spark flame, to just closely existing in operation
Very close staff and neighbouring staff cause the scaling loss of personal injury and periphery electrical equipment, while form grid company
Safety responsibility event.Once occurring 5 or 6, then the potential safety hazards such as operating CT secondary circuits multipoint earthing may be caused.
Therefore, routine test terminal lacks anti-error function, can not realize wiring protection function, fully rely on staff's
Subjective control, error probability height occurs, and it is serious that consequence once occurs.Major safety risks be present, can not meet to keep the safety in production
It is required that, it is necessary to research and develop the testing terminal of new structure.
A kind of connecting terminal apparatus with wiring protection has been designed with, the is fixedly installed respectively at the both ends of bridge joint mechanism
One splice protector, the second splice protector, screw normal displacement is stirred when bridge joint mechanism, when realizing disconnection, the first wiring
Guard member covers short circuit sleeve openings；When bridge mechanism stir screw normal displacement realize connection when, the second splice protector
Cover test cartridge opening.But wrong displacement without reason surprisingly occurs sometimes for this bridge joint mechanism, causes protection to be lost one's head, draws
Play potential safety hazard.
