Technical field the utility model relates to a kind of Medium Voltage Switchgear bus bar side cable connector plug assembly, can be under the prerequisite of not changing former switch cubicle design by this plug-assembly, cable is installed to bus bar side, is made things convenient for user installation and guarantee versatility, the interchangeability of switch cubicle.
Background technology is present, and conventional bus bar side cable is connected with mode in following two: 1. connect by promoting cabinet; 2. connect by the bus bar side cable sleeve.Contrast above two kinds of methods, be analyzed as follows:
Scheme 1: adopt to promote the cabinet connection, need to increase by one and promote cabinet, after cable is connected to cable sleeve, be connected on the bus by promoting cabinet, this scheme has not only increased the expense of equipment investment and installing space investment, and when customer requirements is installed voltage transformer, need to increase the voltage transformer cabinet in addition voltage transformer is installed, increased investment again, and difficulty is installed, reliability is low.
Scheme 2: the connected mode that adopts the bus bar side cable sleeve, this scheme needs switch cubicle is carried out particular design, provide different composite designs by customer requirements, therefore switch cubicle lacks versatility and interchangeability, the user need order the cupboard of corresponding particular design by the arrangement of switch cubicle, is unfavorable for standardized management.
Summary of the invention is for solving the weak point of above two schemes, the utility model provides a kind of connectivity scenario of direct bus bar side cable, not only solved the technical barrier of the direct connection bus of cable, and need not to increase the lifting cabinet, and can be connected directly to voltage transformer, and solved the problems such as versatility, interchangeability of switch cubicle, and need not to revise the design of switch cubicle body, this cable can be installed on arbitrary the switch cubicle that the user orders.
The purpose of this utility model is to adopt following technical scheme to realize:
A kind of Medium Voltage Switchgear bus bar side cable connector plug assembly, it comprises: plug, conducting rod, back plug, bonnet, patch bay and plug fixed head, described plug adopts silicon rubber to make, this plug is connected two parts by the bus connection and forms with cable, its median generatrix coupling part and cable segment connector are that hollow is communicated with, cable is penetrated by cable segment connector and is connected with conducting rod in being placed on the bus coupling part, and the other end of conducting rod is connected the contact engagement with switch cubicle; The head of described bus coupling part is interior wimble structure, and the length of this bus coupling part is greater than the installation length of switch cubicle Up Highway UHW joint sleeve; Described back plug is installed in the rear portion of bus coupling part, and bonnet covers on the plug of back.
Back plug is a female thread structure, and this back plug is connected bonnet on the bonnet with the double end fastening bolt.
The inner cone tapering of described bus coupling part head is 9 ° ± 0.5 °.
Described cable plug adopts the silicon rubber extrusion modling, and the relative density that is used to make the silicon rubber of plug is 0.98, hardness is that Shao Shi A 20～95, hot strength are that 3.45～10.45Mpa, serviceability temperature are-120～280 ℃.
The outer surface of described plug scribbles semi-conductive layer, and the main component of this semi-conductive layer is a carbonization rubber.
The length of described bus coupling part is greater than the length 8～9mm of switch cubicle Up Highway UHW joint sleeve.
Medium Voltage Switchgear bus bar side cable connector plug assembly described in the utility model, utilize former Medium voltage switch or circuit breaker bus joint sleeve cashier's office in a shop, utilize good insulation property of silicon rubber and excellent sealing performance, wimble structure in adopting, certain pressure is pressed in the root of inner cone, guarantee that the inner cone outer surface closely contacts with sleeve pipe, guarantees to satisfy electric insulated enclosure requirement.Cable connector plug assembly of the present utility model needing can conveniently be used for cable to be connected to each scheme of bus, even on-the-spot modification scheme also can not need be changed switch cubicle cable directly is installed.Compare former scheme 1, but each switch cubicle cost saving does not wait for 10000～20000 yuan; Compare former scheme 2, then need not to change former switch cubicle design, increased the standardization level of product.

Embodiment is further described embodiment of the present utility model below in conjunction with drawings and Examples:
Shown in Figure 1 is the structural representation of plug 5 in the utility model, and Fig. 2 is the front view of Fig. 1.This plug is made up of bus coupling part 51 and cable segment connector 52 two parts, can adopt the extrusion modling of silicon rubber one glue during making, and is as follows to the performance requirement of silicon rubber:
| Relative density | Hardness (Shao Shi A) | Hot strength (Mpa) | Serviceability temperature (℃) |
| 0.98 | 20～95 | 3.45～10.45 | -120～280 |
Fig. 3 is connected to structural representation on the switch cubicle bus with cable connector plug assembly of the present utility model with cable.The cable connector plug assembly comprises plug 5, conducting rod 7, back plug 10, bonnet 11, patch bay 4 and plug fixed head 6.
See also Fig. 1, Fig. 2, Fig. 3, bus coupling part 51 and cable segment connector 52 are that hollow is communicated with, cable 13 can be penetrated by cable segment connector 52, be connected with the conducting rod 7 that passes bus coupling part 51 by cable terminal 12, the other end of conducting rod 7 is connected contact 1 engagement with switch cubicle, the structural representation of conducting rod 7 as shown in Figure 4.The head of described bus coupling part 51 is interior wimble structure, its inner cone tapering requires in 9 ° ± 0.5 ° scope, the outer surface of plug 5 scribbles semi-conductive layer, the main component of this semi-conductive layer is a carbonization rubber, has conductivity, thereby can be used as ground connection, the outer surface of plug 5 is tangible behind the installation and operation.
As shown in Figure 3, in the bus joint sleeve 2 on the plug 5 insertion switch cubicles 3, an end of the non-crimping cable of conducting rod 7 is connected contact 1 engagement with switch cubicle.Because during design, the length of plug 5 Up Highway UHW coupling parts is longer than the installation length of sleeve pipe 2, the 8～9mm that generally will rectificate, so the bus coupling part can't be inserted in the sleeve pipe 2 for 51 this moments fully.Patch bay 4 is installed on the switch cubicle 3, and installation plug fixed head 6, when the bolt of fastening plug fixed head 6, plug fixed head 6 can compress plug 5, because we have adopted the raw material of silicon rubber as plug 5, this material has good insulation property and elasticity, therefore under this horizontal pressure force, because there is certain tapering on plug 5 surfaces, this horizontal pressure force can make plug 5 can bear perpendicular to the surface and be parallel to two surperficial partial pressures, plug 5 meeting pressurized diameter expansion, but contraction in length, make between bus joint sleeve 2 and the plug 5 to have had certain pressure, the two closely contacts by this pressure, and assurance can be born the specified electric parameter of switch cubicle 3.
Then cable 13 and stress cone 14 are installed, cable terminal 12 is connected with cable 13 by cold weld, the parts of installation is installed in the plug 5 cable terminal 12 and conducting rod 7 crimping, fastening stud 8, clamp nut 9 can be finished being connected of bus on cable 13 and the switch cubicle 3, installs back plug 10 at last again, back plug 10 designs for internal thread, can be connected with double end fastening bolt 8, cover bonnet 11 again, back plug 10 and bonnet 11 all are universal standard parts.
