Abstract
Disclosed is a bypass connection device for power distribution operation without power off. The bypass connection device comprises two flexible leading down cables which are connected to two ends of a power main line respectively, the other ends of the two flexible leading down cables are connected with a cable butt box respectively, a power cable is connected between the two cable butt boxes, and a by-pass switch is in a serial connection with each of the two flexible leading down cables. According to the bypass connection device for the power distribution operation without power off, perfect butt joint between the flexible cables and common cables is achieved, and the problem that the power distribution operation without power off at a long strain section is difficult to achieve is solved. The bypass connection device has the advantages of being simple in structure, convenient and reliable to use, low in equipment cost, not easy to damage, and the like.
Description
Technical field
The utility model relates to a kind of bypass jockey of power industry distribution uninterrupted operation.
Background technology
Present power matching network bypass operation all adopts flexible cable to carry out, and promptly connects the two ends of electric power main line respectively with long flexible bypass cable two ends, and the centre is connected to a branch line T and connects switch.Because flexible bypass cable cost is expensive, so the distance of power matching network uninterrupted operation has mainly received the restriction of flexible bypass cable length.At present domestic and even power matching network bypass operation that take in the power industry in the world all is to adopt to draw down flexible cable and carry out the transition to flexible bypass cable after through switch, realizes the bypass to former supply line.Because the flexible cable expensive, be prone to impaired, joint length is short, factors such as flow chart complicacy are put in exhibition, restricting power matching network bypass operation carrying out at home always, thereby restricting power supply reliability.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that prior art exists; And provide a kind of common cable that mainly utilizes to replace flexible bypass cable; Can solve preferably power matching network bypass implement cost high, be prone to impaired, exhibition and put shortcomings such as flow chart complicacy, be the bypass jockey of the power matching network uninterrupted operation that power consumer provides reliably, quality power provides strong carrier.
The purpose of the utility model is accomplished through following technical scheme; It includes two flexibilities that are connected to electric power main line two ends and draws cable down; The other end of cable was connected with a cable butting case separately under these two flexibilities were drawn, and between said two cable butting casees, was connected with a power cable.
Under drawing, described two flexibilities are serially connected with a by-pass switch separately on the cable.
The utility model has been realized the perfection butt joint of flexible cable and common cable, has solved the difficult problem that the power matching network bypass operation of long strain section is difficult to realize; Have simple in structurely, easy to use, reliable, equipment cost is low, is difficult for characteristics such as impaired.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
To combine accompanying drawing that the utility model is done detailed introduction below: shown in Figure 1; The utility model includes two flexibilities that are connected to electric power main line 1 two ends and draws cable 2 down; The other end of cable 2 was connected with a cable butting case 3 separately under these two flexibilities were drawn, and between said two cable butting casees 3, was connected with a power cable 4.
Under drawing, two flexibilities shown in Fig. 2 are serially connected with a by-pass switch 5 separately on the cable 2.
The utility model has been realized flexible cable is docked with present domestic distribution common cable in usefulness through common cable butt joint case.
Claims (2)
1. the bypass jockey of a power matching network uninterrupted operation; It includes two flexibilities that are connected to electric power main line two ends and draws cable down; The other end of cable is connected with a cable butting case separately to it is characterized in that drawing described two flexibilities down, between said two cable butting casees, is connected with a power cable.
2. the bypass jockey of power matching network uninterrupted operation according to claim 1 is characterized in that described two flexibilities are drawn down to be serially connected with a by-pass switch separately on the cable.
