Description
Technical field
The present invention relates to outdoor electrical equipment technical field, especially a kind of termination rack for being suitable to ring main unit in-situ reformation.
Background technology
Distribution becomes last link in providing and delivering as electric energy hair, has very important effect in power generation,
Due to historical reasons, the automaticity of past controller switching equipment is not high.With expanding economy and growth in the living standard, to supplying
Electricity quality and reliability propose requirement higher, and after large-scale two-channel filter banks terminate, the layout of power distribution network is optimized,
The reliability of further raising power distribution network is needed, high-caliber distribution network automated, the automation to old equipment is realized comprehensively
Transformation is also just all the more urgent.
Old ring main unit division function is normal, can normally use, if directly by old ring main unit eliminate scrapping treatment
Huge waste will be caused.It is to borrow the new ring main unit number platform of former ring main unit producer according to conventional way, old ring main unit is replaced,
Power failure replacing is carried out again after old ring main unit is returned into factory's transformation.But the old ring main unit that current some Utilities Electric Co.s install is respectively many
Individual manufacturer production, because single producer's ring main unit quantity is few, ring main unit producer does not provide replacement service.Therefore how looped network is realized
The intellectualized reconstruction on the spot of cabinet turns into the significant technology issues for facing at present.
Current majority is used and installed again by old ring main unit a termination rack, wherein placing required PT, CT, DTU
Deng, and the annexes such as terminal block are set.But the terminal part of the terminal block of the termination rack of outdoor installation uses double-row type terminals
Son, such as, in binding post substrate one row's screw type binding post of upper and lower each setting, middle external linear connecting copper bar will
Corresponding two binding posts of upper and lower row are coupled together, then are locked in input and output end respectively with pad and nut upper and lower
Two row's binding posts.But the space needed for this double-row type connecting terminal block volume is big is than larger, for in-situ reformation, no
Beneficial to effective utilization in space.Also there is the terminal of part using single row type wiring, input is connected on terminals simultaneously with output end
On the same screw type binding post of submounts, then with pad and nut check.Although this single row type connecting terminal block is saved
Space, but may in wiring, contact surface laminating is bad, contact resistance can increase, superheating phenomenon occur, or even can draw
