Abstract
The utility model in particular relates to a 10kV power cable tapping box capable of realizing cable butting. The 10kV power cable tapping box comprises a box body, a bi-pass sleeve, cable plugs, a bi-pass sleeve bracket, a cable gripper, a ratguard and a channel steel pedestal. In the box body, the bi-pass sleeve bracket is used for fixing the bi-pass sleeve cast by epoxide resin, installation positions for one group of cable plugs are reserved respectively at two sides of the bi-pass sleeve bracket, two ends of the fixed bi-pass sleeve are respectively provided with the cable plugs, the channel steel pedestal is provided with the cable gripper for fixing an installed cable, and the detachable ratguard is arranged on the upper surface of the channel steel pedestal. Compared with the prior art, the 10kV power cable tapping box is more reasonable in structure and more economical and practical.
Description
Technical field:
The utility model relates to the electric cable accessories technical field of using in the power cable engineering, refers in particular to a kind of 10kV power cable tapping-off case of realizing cable butting.
Background technology:
At the 10kV distribution network, the most common by the cable line that many (every be about be 200-400 meters) cables connect to form, and the connection between the cable adopts cable intermediate joint also the most frequent.Cable intermediate joint has experienced the development course of epoxy resin casting type, thermal shrinkage type, silicon rubber prefabricated, and silicon rubber prefabricated transition joint at present is the most popular with users, and reason is exactly because silicon rubber has the premium properties that other material does not have.Adopting the transition joint connected mode is exactly to recover the primary characteristic of cable, be disposable transition joint, because this transition joint operates in the cable trough, this just proposes extremely strict requirement to the sealing of transition joint, and the electric field stress at cable joint place is handled has uncertainty.The reliability of this cable intermediate joint is strong especially to the dependence of construction technology, as seals badly, and quick-fried phenomenon can take place for cable joint immersion.The electric field stress of joint is handled bad, and minor insulation punctures also can make the cable joint place blast.In addition, non-dismountable because this transition joint is disposable, make troubles for the troubleshoot in the cable line.With regard to the existing technology of China, the fault that searches cable line is very time taking, if segment lookup then be difficult to find the fault point not.So, reduce artificial factor in the cable connection procedure as far as possible in order to improve 10kV cable line reliability of operation, shorten the repair time of cable line, develop very necessity of a kind of transition joint that can reach this purpose!
Summary of the invention:
The utility model purpose is overcoming the deficiencies in the prior art, and a kind of 10kV power cable tapping-off case of rational in infrastructure, the economical and practical cable butting realized is provided.
For achieving the above object, the technical scheme that the utility model provides is: include casing, bilateral sleeve pipe, cable plug, bilateral casing support, cable clip, ratguard, channel-section steel base, it is characterized in that: the bilateral sleeve pipe of casting with bilateral casing support retainer ring epoxy resins in the casing, the installation site of one group of cable plug is respectively reserved on the both sides of bilateral casing support, cable plug is installed at fixing bilateral sleeve pipe two respectively, cable clip is set on the channel-section steel base is used for fixing mounted cable, dismountable ratguard is arranged on the upper surface of channel-section steel base.
The utility model utilizes the stainless steel casing as detachable transition joint protecting sheathing, installs on the ground, can satisfy the condition of outdoor operation fully.The running environment of transition joint is improved running environment on the ground from underground making into, improved coefficient of safety.Bilateral sleeve pipe and silicon rubber prefabricated cable terminating plug are connected into a dismountable transition joint, this mode has made full use of property-ageing resistace, high resiliency of silastic material etc., for convenience detach, can repeat to install, the circuit sectional that in a single day breaks down just detects, and has shortened detection time.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described further,
Accompanying drawing 1 is a structural representation of the present utility model.
Embodiment:
See shown in the accompanying drawing 1 that detachable composite type transition joint utilizes 1 protection of stainless steel casing, can satisfy outdoor running environment.Adopt the bilateral sleeve pipe 2 of bilateral casing support 4 retainer ring epoxy resins casting in the stainless steel casing, the installation site of one group of cable plug 3 is respectively reserved on the both sides of bilateral casing support 4, the structure of opening the door in both sides, cable plug 3 is installed at fixing bilateral sleeve pipe two respectively, utilize silicone rubber for cable plug 3 and bilateral sleeve pipe 2, stress cone and plug, cable and stress cone all are interference fit; Cable plug and bilateral sleeve pipe adopt bolt matable, and the detachable transition joint that such two cover cable plugs 3 are formed just has excellent sealing performance, water resistance.Cable clip 5 is set on channel-section steel base 7 is used for fixing mounted cable, install two altogether, the fixing cable on bilateral sleeve pipe 2 both sides respectively, for reducing the pulling force of mounted cable to the bilateral sleeve pipe, the upper surface of dismountable ratguard 6 at channel-section steel base 7 is set, the convenient installation and sealing can prevent entering and can effectively reducing moisture of toy.
Present embodiment is transferred to the running environment of transition joint on the ground from underground, disposable in the past, non-removable transition joint converts to dexterously and can repeat to install detachable knockdown active transition joint, installation environment and running environment have been improved, improved coefficient of safety, segmentation detection for faulty line can realize under the condition of not destroying electric cable accessories.
The embodiment of the above is preferred embodiment of the present utility model only, is not to limit practical range of the present utility model with this, so the equivalence that all shapes according to the utility model, structure and principle are done changes, all should be covered by in the protection range of the present utility model.
