Background technique
In the new era that economy is grown rapidly, network load constantly increases, wants to substation secondary device protective device Ask also higher and higher, since the average life span of protective device is 8 years, current many old protective device agings are serious, Be unsatisfactory for current service condition, need it is whole order retainers, servants, etc. to retire out, newly screen is in place, transform new protective device as;It is protected in substation It is most nerve-wracking to surely belong to disconnecting for small bus in the work of shield screen replacement, in face of increasingly heavier transformation task, improve small Bus disconnects efficiency and can improve the replacement efficiency of protection screen.
Small bus is to control the shared remittance product line such as power supply, protection power source, alternating voltage, AC power source, in secondary circuit In have a decisive role, due to its special role, determine its generallyd use screen top arrangement mode, protecting During transformation, capital construction, enlarging, screen pushes up disconnecting for small bus and has become an important factor for influence is kept the safety in production;Of the remote past Substation structure in, the connection type of small bus is generally ring network power supply mode, and the connection of small bus between each protection screen is tight It is close, it may be said that during replacing protection screen, to pull one hair and move the whole body to the processing of small bus.
It was found that the auxiliary bus-bar joint on protection screen top there are many drawbacks now in transformation process, small bus is being disconnected When to work bring great inconvenience;Firstly, the volume of auxiliary bus-bar joint is heavy, thick big, and each protection screen top Small bus mostly use solid exposed copper rod, stick spacing interval is smaller, when disconnecting operation it is extremely cumbersome;Secondly, changing When needing wiring during making, the hand of staff is hard to reach the bottom of auxiliary bus-bar joint, and uses screwdriver the turn of the screw Operation difficulty is larger, and when wiring is also required to be processed into conducting wire both ends on the ring-like screw that can be just connected to terminal two sides or bottom side, And this conducting wire process is time-consuming and laborious;In the connection procedure of conducting wire and screw, if poor contact or loosened, have It may cause protective device power loss or do not acquire alternating voltage, when electric system is broken down, it will cause to protect The malfunction or tripping of protection unit;Finally, often having when small bus electrification disconnects and connecing multiple conducting wires on an auxiliary bus-bar joint Situation, although staff's reasonable line arrangement, operates with caution due to being spaced smaller, narrow space between auxiliary bus-bar joint, but still has The risk of Danger Electric shock risk and short circuit accident occurs, safety coefficient is lower, seriously affects the normal operation of substation.
Utility model content
The utility model is in order to overcome the deficiencies in the prior art, technical problem to be solved are as follows: provide one kind It supports small bus copper rod and terminal plug to connect, and has the secondary screen top auxiliary bus-bar joint of double-layer wiring structure;In order to solve Above-mentioned technical problem, the technical solution adopted in the utility model are as follows: secondary screen top auxiliary bus-bar joint, including insulated terminal, it is described One end of insulated terminal is provided with terminal connections hole, and the terminal connections hole includes upper layer wiring hole and lower layer's wiring hole, described Conducting wire can be inserted in upper layer wiring hole and lower layer's wiring hole, and fixed by fastening screw;
Terminal breakpoint is additionally provided in the middle part of the insulated terminal in flakes, the terminal breakpoint passes through in flakes fastens spiral shell in flakes Silk is fixed on insulated terminal;
The other end of the insulated terminal is provided with copper rod socket, is provided with a pair of of intermediate plate on the inside of the copper rod socket, The intermediate plate can adjust mutual distance by wire clamp screw;
The insulated terminal is connected and fixed by copper rod and another insulated terminal.
The quantity of the upper layer wiring hole is at least three, and the quantity of lower layer's wiring hole is at least three.
What the utility model had compared with the existing technology has the beneficial effect that the utility model is protected for substation secondary The improvement that the auxiliary bus-bar joint structure on shield screen screen top carries out, changes the connection type of tradition small bus copper rod and terminal, by original Crimping mode be changed to plug mode, while being double layers of terminals by terminal design, expand more wiring holes for auxiliary bus-bar joint, And design all fastening screws above terminal, the fastening tools such as screwdriver are easy to use, safe and reliable and energy is efficient Complete more changing jobs for protection screen;Terminal structure provided by the utility model compared to conventional terminal use enhanced convenience, Safety, conventional terminal is time-consuming and laborious to protection screen terminal block patchcord, is absolutely unsafe, and uses the double layers of terminals knot of the utility model Structure, which only needs to be inserted into after the end of a thread, to be achieved that screw tightening and is reliably connected;The screw that the utility model uses is existing Good application has been obtained in substation's technological transformation, test adjustment work, can greatly shorten working hours, improve work Efficiency;Can slidably carrying out in flakes in the case where not changing circuit connecting wire to circuit for the utility model setting is electrical Isolation, it is possible to prevente effectively from because short circuit caused by human factor or electric shock.
