Embodiment
Further illustrate technical scheme of the present invention below in conjunction with concrete enforcement.
1. good for each core insulation of control cables that guarantees to lay, before laying, control cables should check insulation resistance (as shown in Figure 9, using 500V megohm meter to measure)
For the cable that metallic sheath, screen or armouring are arranged:
Multicore cable, should be respectively be connected and be measured all the other cores and metallic sheath or screen or armour with regard to each core; Measure insulation resistance between multicore cable core and shielding, should will be measured shielding after all core parallel connections.
Non metallic sheath, non-shielding or without the cable of armouring:
Multicore cable is measured after should connecting all the other cores with regard to each core respectively.
The 10 core cables of the Digital ID shown in Fig. 9 of take are example: by 2～No. 10 line core with after the shielding drainage thread is in parallel and measure between the Line 1 core; By 3～No. 10 line core with the shielding drainage thread in parallel after and between No. 2 cores, measure, get rid of the single line core at every turn, by that analogy, until all be completed.The insulation measurement result all should be more than 200M Ω, otherwise should search reason.
2. control cables is pasted the temporary cable board before and after laying
In the past, carrying out before and after the cable laying construction is all to be tied formal cable card, the one, easily cable card is hung and caused loss in the cable laying process, the 2nd, when making cable termination stripping cable, cable card is tied position in the stripping scope and removes and cause confusion or lose.Therefore, employing is printed on large-scale Indexing tab by cable number, model, specification, voltage, the beginning and the end place device name or, on the A4 copy paper, at least the same form is two, sticks on respectively the control cables two ends of laying, as shown in figure 10.Longer cable also need be pasted in middle part, then uses the tight looping of wide adhesive tape two-layer, to cement and to estimate clear being as the criterion.The particular location of pasting should be two ends and deducts the additional length place, is positioned at outside the stripping scope.The additional length of cable is with reference to table 1.The main consideration that the temporary cable board sticks on herein is, at cable laying, cable termination stripping, terminals, makes, cable tie is fixed and the overall process of wiring can be not destroyed and lose, to the last of formal cable card replacement.Correct for guaranteeing the stickup of temporary cable board, should be responsible for by the special messenger.
Additional length when table 1 35kV and following cable laying tolerance
Cable terminal stripping cable jacket, penetrate the wire size pipe
Control cables has laid put in place (dish, screen or equipment place), and the cable arrange-line before terminals are made completes and colligation is temporarily fixed, and it is reserved that cable length meets the longest standby core, cuts unnecessary length.
As the control cables insulated wire cores is numeral flag, can along continuous, carry out according to normal cable connection operation, make (comprise earth connection draw), cable as stripping cable, terminals and fix, wire harness colligation etc., need be in strict accordance with cable core since 1 natural numerical order from small to large when arriving the school line and wearing wire size plumber order, with the terminal board natural numerical order from small to large corresponding wire size pipe that penetrates one by one, as shown in figure 11.Then carry out following operation, as terminal separated time, wiring, ground connection, list, the work progress such as arrangement.
When the control cables wiring, head connect an end and did not need the school line in the past, and it is larger that the taking out of core connects randomness, when connecing the other end and head connect end and carry out the school line, connect end secondary wire size pipe with head and be as the criterion.If do not need the school line while making other end wiring, firstly connect an end and must penetrate according to certain rule the wire size pipe, handle and get final product by this rule during other end wiring.
As the multi-core controlled cable insulated wire cores is every layer of standard core with distinct color, when most of cores are the same color (as shown in Figure 4), at first long to cable socket stripping oversheath, steel armour and inner covering 50～80mm, expose whole cores, but must keep the original arrangement of cable core, must not be loose, to keep the original arrangement of cable core.The standard core that has distinct color with outermost layer penetrates wire size pipe 1, and sequence penetrates wire size pipe 2, wire size pipe 3 by the root core in the direction of the clock, until this layer line core has all been worn, natural number is again from second layer standard core, by that analogy until all worn.When connecing the cable other end, the standard core that still with outermost layer, has a distinct color penetrates wire size pipe 1, and penetrate wire size pipe 2, wire size pipe 3 by counterclockwise sequence by the root core, by that analogy until all worn, worn the core of wire size pipe and all made a call to turning one's head of an about 10mm, come off to avoid the wire size pipe.
The numeral flag cable core is by 1,2,3 ... natural numerical order, corresponding one by one with terminal board natural numerical order from small to large, and penetrate the secondary wire size pipe of answering in contrast.Color-coded cable core, the core that the outermost layer of take has distinct color is 1, in cable socket core 2,3, the 4 natural orders arrangements in the direction of the clock of central station of floating dock side, dish cabinet side, mains side, control side; At the cable socket core of equipment side, power side, controlled side on the spot, by 2,3,4 natural orders counterclockwise, arrange.
While running into different types of multi-core controlled cable, can adopt the method be explained by reference to the accompanying drawings in summary of the invention to position and number.
While being color-coded, after all cores are put on the wire size pipe, just can start follow-up operation when the cable insulation core, as continue stripping cable jacket, terminals making etc., after the terminal separated time completes, the wire size pipe need be smoothed out with the fingers to suitable position, cut the core of unnecessary length, finally complete wiring work.
Above the present invention has been done to exemplary description; should be noted that; in the situation that do not break away from core of the present invention, the replacement that is equal to that any simple distortion, modification or other those skilled in the art can not spend creative work all falls into protection scope of the present invention.
