Description
Technical field
The utility model is related to wire connection terminal field, more particularly to a kind of wire connection terminal dress with auxiliary connection protection
It puts.
Background technology
Secondary returning is usually realized with wire connection terminal 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 stirring screw, can manual toggle bridge joint mechanism,
Realize that connecting terminal apparatus both ends are in " connection " or "off" two states；Stirring screw then will locked and fixed in flakes above and below
In current state, the effect of connection or disconnection is 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 outer diameter, for testing when is easily and reliably inserted into and pulls out temporarily
Go out test wire.It is outside experiment line jack or short circuit line jack plus sleeved generally in order to fix the test wire plug of insertion, referred to as
For test cartridge or short circuit sleeve.The wire connection terminal 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
Wire connection terminal between bridge joint mechanism position and connection status.
In relay protection of power system, particularly current loop in differential relaying panel, carry out bus differential protection device or from
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 in 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 protective device or backup auto-activating device periodic inspection are tested, due to the specialized capability of staff individual 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 restore bridge joint mechanism to " connection " state and just directly remove shorting stub；
3rd, protection side joint line sleeve accidentally is inserted into shorting stub, stirs bridge joint mechanism later to "off" state；
4th, test wire is accidentally inserted into CT side joint line sleeves, stirs bridge joint mechanism later 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 restore to " connection " state.
More than 1 to 4 any maloperation, directly artificially cause CT second open circuits, running 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 security risks such as running 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
Error probability height occurs for subjective control, and it is serious that consequence once occurs.There are major safety risks, can not meet safety in production
It is required that need the testing terminal of research and development 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 stir screw normal displacement 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, and protection is caused to be lost one's head, is drawn
Play security risk.
