Description
Technical field
This utility model relates to substation field operation and accesses 380/220V power supply supporting operation instrument, is specially a kind of line
Shaft cable universal connector the end of a thread.
Background technology
It is engaged in field operation in transformer station to need to use bobbin cable to access power supply from maintenance power box.In maintenance power box
Access 380/220V power mode, be generally divided into three kinds: (1) directly accesses power supply from band earth leakage protective air switch；(2)
380/220V band earth leakage protective air switch lead-out wire is connected to binding post, accesses power supply from binding post；(3) in maintenance power box
If private jack.
Scene accesses power supply and easily causes power supply short circuit accident, even occurs personnel to get an electric shock, on-the-spot because connecing what power supply occurred
Accident is of common occurrence.Analyze its reason to include: it is relatively low that (1) maintenance power box accesses multiposition at power supply, eyes when accessing power supply
It cannot be directly viewed at air switch binding post.(2) the bobbin cable of onsite application does not has special joint, and directly uses line
End strand copper wire connects.The end of a thread be difficult to insert air switch binding post be also easy to broken lot cause Live line Zero line short circuit.Exist the biggest
Potential safety hazard, concrete common technical problems is divided into:
(1) personnel do not turn off power supply wiring when neglecting wiring, cause person electric shock；
(2) mispick 380V voltage, 220V voltage, is easily damaged equipment, instrument or makes equipment, instrument cisco unity malfunction；
(3) bobbin cable connection be multiply annealed copper wire with maintenance power box air switch wire to terminal time be not easy to connect,
Easily broken lot causes live wire, zero line to touch short circuit by mistake；
(4) lug malcompression during wiring, heating causes Thermal protection action to trip；
(5) zero line, ground wire wrong easily cause earth leakage protective action tripping operation or equipment, instrument cisco unity malfunction；
(6) wire sway touches charging equipment by mistake and causes the accident.
Summary of the invention
This utility model accesses 380/220V power supply for solving current substation field operation, and the measure that scene is taked is simply
Requirement accesses power supply and must two people carry out, and strengthens monitoring, lacks the technological means of necessity, there is many potential safety hazards.And this reality
Can be just that scene accesses a kind of technological means reliably of power supply offer with novel researched and developed bobbin cable universal connector the end of a thread.
This utility model adopts the following technical scheme that realization: a kind of bobbin cable universal connector the end of a thread, including a company
Connection device, described attachment means connects the cable terminals having pair of joint part to be connected with blank area；Connect dress
Put and be also associated with an insulation lanyard；One end of insulation lanyard is connected in attachment means, and the other end of insulation lanyard connects
There is a double-ended clamp.
Double-ended clamp can one be fixed on maintenance power box tank wall, cable is clamped in other end, makes cable access
After power supply curved one " U-bend " (shown in Figure 10) at maintenance power box, prevent at air switch binding post crimping go between stress
Accidents caused with preventing cable from swinging.And original mode of connection is typically simple that cable is entangled in maintenance power box door or door
On handle, the most lack of standardization the most dangerous.
Further, what described blank area included being located in attachment means be flexible coupling lead-in wire and be connected to be flexible coupling and draw
The hard joint of the line other end.
Use custom-designed hard joint, various connection types in both can simultaneously adapting to site examining and repairing power supply box during wiring,
The shortcoming that when can prevent again Stranded cable wiring, easy broken lot causes short circuit.
Further, a charged display device circuit board it is provided with inside described attachment means；On this device front panel
Being provided with charged display lamp, have electric alarm loudspeaker, have electric alarm involution button, LCDs, inside is provided with electrical verification, voltage tester
Loop, the back side is provided with binding post and arranging batteries groove；It is provided with in arranging batteries groove to electrical verification, voltage tester loop and liquid crystal display
The battery of screen power supply.
This utility model also has electric alarm function, is similar to low pressure electroscope, in the case of having electricity, and can sounding light
At warning reminding wiring personnel's wiring charged, prevent non-deenergization from carrying out wiring and cause personnel's electric shock accidents, can realize report to the police
Involution.
This utility model also has test voltage function, can prevent 380/220V wrong.What maintenance power box accessed is three
Phase power supply, so two kinds of voltages of desirable 220/380V.Wiring is followed by the supply voltage that informant person can be shown in real time by liquid crystal display screen
Observe wiring the most correct, prevent phase-phase, phase-zero wrong from taking wrong voltage and damage electrical equipment, instrument or make equipment, instrument
Cisco unity malfunction.Corresponding circuit uses the ac voltage detection circuit of circuit tester.
Further, the binding post at the described charged display device back side includes two groups of binding posts, and two groups of binding posts are as electricity
Cable terminals, one group is connected with blank area, and another group is for being connected with cable；Often group binding post all includes A phase connection
Connect terminal, C of post, B connects terminal, N binding post and ground binding post.
Designed universal connector the end of a thread is installed at ordinary times on bobbin cable and acts the effect being similar to " plug ".Live wire, zero line,
Ground wire is yellow according to A() B(is green) C(is red) N(is blue) the principle of (black) by separate wiring, can effectively prevent wrong zero line and ground wire,
Cause air switch breaking or equipment, instrument cisco unity malfunction.
Bobbin cable universal connector the end of a thread structure designed by this utility model, attainable function and technique effect:
(1) blank area: because 380/220V Quick air switch is typically all disposed within maintenance power box bottom, due to space
Limited, wiring personnel squat down on the ground, and lug is fastened to air switch terminals the hardest.Bobbin cable uses that multiply is soft connects
Head, during wiring, easy broken lot causes short circuit, or multiply connecting hose easily breaks, loosen and cause heating, designed by this utility model
Blank area uses hard joint, can first carry out positioning fastening again.
This blank area includes hard joint and the lead-in wire two parts that are flexible coupling.The lead-in wire that is flexible coupling is provided with insulating sheath, with design
Hard joint crimping fastening.
(2) there is electric alarm part: electric alarm function can have been realized, prevent personnel from neglecting non-deenergization and carry out wiring and cause
Personnel's electric shock accidents, can realize alarm sound involution.
(3) test voltage part: magnitude of voltage (220/380V) display function in real time can be realized.
(4) lanyard: for connecting the insulation lanyard of double-ended clamp.
(5) double-ended clamp part: cable can be realized and fix.
Owing to accessing 380/220V power mode disunity in station power supply box, the bobbin that on-the-spot each specialty uses
The joint that cable is the most unified.But use (three-phase or biphase) Stranded cable copper cash directly to access power supply at power supply, both
Lack of standardization the most dangerous.Bobbin cable universal connector the end of a thread designed by the application has been filled up when field operation accesses maintenance power supply and has been deposited
This technological gap.
