Abstract
The invention discloses a T-type connection copper bar connecting device in a low-voltage meter box matched with a user. The T-type connection copper bar connecting device comprises a T-type connection copper bar, a copper pig tail and a plastic copper wire. The plastic copper wire is embedded in the copper pig tail, and the copper pig tail is fixedly connected with the T-type connection copper bar through machine screws. The T-type connection copper bar connecting device has the advantages that the copper pig tail is used for connecting the copper bar and a copper cable, safety and reliability are achieved, in addition, the plastic copper wires are in pressure joint with the copper pig tails with the square numbers corresponding to that of the plastic copper wires, the safety accidents that devices are burned due to too large currents are effectively avoided, operation and maintenance cost are saved, safe and stable operation of electric power facilities is guaranteed, and the T-type connection copper bar connecting device is suitable for being applied and popularized in large scale.
Description
Technical field
The present invention relates to electric power low-voltage distribution professional skill field; The T particularly relating in the table case of the supporting family of low pressure resident connects copper bar connecting device.
Background technology
To connect copper bar be 30*1.2 to T by U word attachment strap, electric wire is moulded to copper cash and connect copper bar with T and be connected in existing household table table case, gauging table has 20A, 30A, 40A and tetra-kinds of models of 60A, all adopt off-gauge U word attachment strap from 16 squares of copper cash to 70 square copper cash open-wire line, line and screw directly curl up, and when line is thin, need to fold, and are easily pressed loose when line pressure after folding is tight, thick line compress time in the edge that releases, when electric current by time, overheatedly more easily cause and release, security incident occurs frequently; In addition, electric current increases causes copper bar current-carrying capacity excessive, very easily burning apparatus, particularly also increase gradually newly-built community in recent years, and scale is also increasing year by year, and potential safety hazard is also increasing, finding because off-gauge U word attachment strap causes crimping unreal through checking, is also the main cause of potential safety hazard.
Summary of the invention
Technical matters to be solved by this invention is, a kind of electric power facility safety that ensures is provided, and the T that meets productive life needs connects copper bar connecting device.
The technical solution adopted in the present invention is: the T in the table case of the supporting family of a kind of low pressure resident connects copper bar connecting device, comprises, T connects copper bar, copper lug and moulds copper cash; The described copper cash of moulding embeds copper lug, and copper lug connects copper bar with T and is fixedly connected with by machine screw.
It is 30*4 that T below four epi-positions connects copper bar, and it is 60*6 that T more than five epi-positions connects copper bar; Mould the square number of copper cash and the square number of copper lug is corresponding identical.
The invention has the beneficial effects as follows: owing to having used copper lug that copper bar is connected with copper cable, safe and reliable, in addition, copper cash is moulded the square number of copper cash and the corresponding crimping of the square number of copper lug, effectively avoid the generation of the security incidents such as the excessive equipment burnout of electric current, also save O&M cost, ensure electric power facility safe and stable operation, be applicable to large-scale promotion application simultaneously.
Brief description of the drawings
Fig. 1 is that in the table case of family of the present invention, novel T connects copper bar schematic diagram.
In figure:
10. T connects copper bar 20. copper lugs 30. and moulds copper cash 40. machine screws.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail:
As shown in Figure 1, the T in the table case of the supporting family of low pressure resident of the present invention connects copper bar connecting device, comprises, T connects copper bar 10, copper lug 20 and moulds copper cash 30; The described copper cash 30 of moulding embeds copper lug 20, and copper lug 20 connects copper bar 10 with T and is fixedly connected with by machine screw.It is 30*4 that T below four epi-positions connects copper bar, and it is 60*6 that T more than five epi-positions connects copper bar, also can strengthen according to actual needs the current-carrying capacity of copper bar; The main line that outside line enters table case is installed on copper bar, and with the suitable table line of epi-position number, be not limited in 2 table lines shown in figure; Copper lug has national standard, have size difference according to carried square number difference, mould the square number of copper cash and the square number of copper lug is corresponding identical, as 16 squares of lines adopt 16 squares of copper lug crimping, 25 squares of lines adopt the corresponding crimping such as 25 squares of copper lug crimping, and this structure crimping is firm, effectively avoid the generation of the security incidents such as the excessive equipment burnout of electric current, save O&M cost, ensure electric power facility safe and stable operation, provide safety guarantee to citizen.
The present invention is owing to having used copper lug that copper bar is connected with copper cable, safe and reliable, in addition, copper cash is moulded the square number of copper cash and the corresponding crimping of the square number of copper lug, effectively avoid the generation of the security incidents such as the excessive equipment burnout of electric current, also save O&M cost, ensure electric power facility safe and stable operation, be applicable to large-scale promotion application simultaneously.
Claims (2)
1. the T in the table case of the supporting family of low pressure resident connects a copper bar connecting device, it is characterized in that, comprise, T connects copper bar, copper lug and moulds copper cash; The described copper cash of moulding embeds copper lug, and copper lug connects copper bar with T and is fixedly connected with by machine screw.
2. the T in the table case of the supporting family of low pressure resident according to claim 1 connects copper bar connecting device, it is characterized in that, it is 30*4 that the T below four epi-positions connects copper bar, and it is 60*6 that T more than five epi-positions connects copper bar; Mould the square number of copper cash and the square number of copper lug is corresponding identical.
