Abstract
The invention discloses a kind of recognition methods of linear quadratic control cable, and secondary control cable of transformer substation is classified according to its function difference, then carries out mounting and installation after different classes of cable cover(ing) is subject into color differentiation, ultimately forms the standard of cable cover(ing) colour recognition.The cable of later stage reorganization and expansion substation laying installs this standard and carries out color discrimination, so as to reach prompting, warn staff to avoid touching operating loop cable, dangerous higher cable by mistake, the possibility of transformer station's irregular operating and human casualty accident is reduced, while improves lookup and takes out, the operating efficiency of payout.
Description
Technical field
The invention belongs to power plant, transformer station, current conversion station linear quadratic control cable management identification technology field, and in particular to one
The recognition methods of kind linear quadratic control cable.
Background technology
National standard and professional standard do not make regulation to secondary control cable of transformer substation sheath color, in each voltage etc.
The conventional substation of level, in current conversion station, stand in cable cover(ing) be black.If a cable channel cover plate or opening are opened at random
Antistatic floor, staff can not accurately judge the information such as function, the whereabouts of every cable, therefore at work can be through
It is commonly encountered following two situations：
1st, in transformation or extension project, operation screen cabinet, equipment mechanism case, extract out in electrical equipment terminal box cable be must
Indispensable action, this work common practice are that several staff rock cable in cabinet, in addition several works
Make personnel and situation rocked according to cable below cabinet in cable duct or cable interlayer to judge which root cable needs to extract out,
Because cable is more below cabinet, arrangement is not very neatly arranged and cable is black, and the staff of lower section judges that cable goes out
Wrong possibility is very high.Operation cable is pullled in the case of error in judgement, then may cause equipment fault, if cable is not
Bright position block can not be extracted and this cable because need of work must extract out when, construction worker may Misuse cable cutter
Cable is cut, protection misoperation or tripping can be caused if protection exit loop, voltage circuit, electric power loop is cut, if cutting
Disconnected recording loop, signal circuit can then influence transformer station and normally monitor, and personal injury thing is likely to occur if current loop is cut
Therefore.
2nd, in the work such as regular maintenance, defect elimination, regular inspection, can run into search the standby core of cable and reversely find the cable,
Determine that cable louding etc. needs to find the work of cable in screen cabinet or terminal box, the method for finding cable at present only passes through electricity
Cable board, and shield cabinet or terminal box inner cable quantity is larger, searching cable more wastes time and energy.
Because by mistake cable touches, miscut etc. occurs industrial accident and happened occasionally in power generation construction field.
The content of the invention
It is an object of the invention to provide a kind of recognition methods of linear quadratic control cable, reaches and is being transported in reduction transformation or enlarging
The operation risk of equipment, the technique effect for improving efficiency of construction.
The present invention is achieved through the following technical solutions：
A kind of recognition methods of linear quadratic control cable, is comprised the following steps：
Step 1. is classified cable by difference in functionality, selects the cable that need to carry out colour recognition, including current loop,
Voltage circuit, control loop, DC loop and other loops；
The sheath of different classes of cable is subject to carry out mounting and installation after color is distinguished by step 2., and current loop is using blue
Color, voltage circuit use yellow, and control loop is using red, and for DC loop using green, other loops use black；
When step 3. is constructed or overhauled, the sheath color of every linear quadratic control cable is checked, according to the cable institute band
Colour recognition simultaneously confirms this cable run, completes the identification of a plurality of cable run.
Further, the sheath of the linear quadratic control cable is made of thermoplastic polyvinyl chloride's sheath material, its thickness
GB/T9330 regulations should be met.
It is an advantage of the invention that：Secondary control cable of transformer substation is classified according to its function difference, then by inhomogeneity
Other cable cover(ing) is subject to carry out mounting and installation after color is distinguished, and ultimately forms the standard of cable cover(ing) colour recognition.Later stage changes expansion
The cable for building substation's laying installs this standard progress color discrimination, and so as to reach prompting, warning staff avoids touching by mistake
Operating loop cable, dangerous higher cable, reduce the possibility of transformer station's irregular operating and human casualty accident, carry simultaneously
Height is searched and taken out, the operating efficiency of payout.
Brief description of the drawings
Accompanying drawing 1 is logic diagram of the invention；
Embodiment
Embodiment
As shown in figure 1, a kind of recognition methods of linear quadratic control cable, is comprised the following steps：
Step 1. is classified cable by difference in functionality, selects the cable that need to carry out colour recognition, including current loop,
Voltage circuit, control loop, DC loop and other loops；
The sheath of different classes of cable is subject to carry out mounting and installation after color is distinguished by step 2., and current loop is using blue
Color, voltage circuit use yellow, and control loop is using red, and for DC loop using green, other loops use black；
When step 3. is constructed or overhauled, the sheath color of every linear quadratic control cable is checked, according to the cable institute band
Colour recognition simultaneously confirms this cable run, completes the identification of a plurality of cable run.
Wherein, the sheath of the linear quadratic control cable is made of thermoplastic polyvinyl chloride's sheath material, and its thickness should accord with
Close GB/T9330 regulations.
This patent increase cable cover(ing) colour recognition the first purpose be deduction and exemption produced because not knowing cable feature touch by mistake,
Miscut, tear operating loop cable open by mistake, cause the possibility of breaker malfunction, tripping or the normal monitoring of influence operator on duty.
Therefore whether cable possessed function may cause breaker malfunction, tripping to come as the cable using colour recognition
Basis for estimation.So cable should be classified by difference in functionality first, the cable that need to carry out colour recognition is selected.Linear quadratic control
Cable is as shown in table 1 by function classification.
Table 1
It is placed in view of cable under cable duct, cable interlayer, antistatic floor, these places are that light is not sufficient enough
Place, so cable cover(ing) color loses the meaning of colour recognition if low key tone is selected, particularly across the ash of a period of time
Dirt accumulates, and is more difficult to distinguish between low key tone and black, and bright-colored gives people a kind of strong visual impact sense.Therefore intend using
More bright-coloured, lightness and form and aspect are higher, and contrast higher red, yellow, blue, green color is known as cable color each other
Other alternate color.Linear quadratic control cable cover(ing) colour recognition is as shown in table 2.
| Cable feature | Current loop | Voltage circuit | DC loop | Control loop | Other loops |
| Cable color | Blueness | Yellow | Green | It is red | Black |
Table 2
Above-listed detailed description is illustrating for possible embodiments of the present invention, and the embodiment simultaneously is not used to limit this hair
Bright the scope of the claims, all equivalence enforcements or change without departing from carried out by the present invention, it is intended to be limited solely by the scope of the claims of this case.
