The problem of disposing and being convenient for O&M.The design form of bus duct is plug and play at present, but because its design and practical application are de-
Section also brings many bus deployment and the puzzlement and inconvenient, the status for causing purpose of design and application not to be inconsistent in operation and maintenance.It is existing
Some buses either fixed-point type or bit architecture is put entirely, continue to use Heuristic Design thinking, and jack box is the one of bus duct
Part is a kind of cantilever beam structure form.Jack box is usually the tension for leaning on itself copper contact pin, is clipped in bus duct interface
Conducting copper realizes grafting.But the existing jack box in bus duct system exists such as in actual use
Lower problem:
1, during the hot plugging of jack box, to guarantee safety inserting, generally require first to carry out zero fire in bus duct
Then the differentiation of line conductor etc. carries out the installation of jack box, however due to the influence of installation environment and personnel's proficiency etc., still
Inconsistent phenomenon occurs when being difficult to avoid that hot plugging.
2, although existing jack box is able to achieve its inserting on bus duct, it can be difficult to guaranteeing that jack box inserts pawl and mother
The good contact of conductor in wire casing, so that plug precision is lower, so that the power-off easily occurred during electric leakage or electricity consumption is asked
Topic.
3, since jack box and bus duct are cantilever mounting structure, therefore in jack box long-term use process, its own weight
Power easily in bus duct conductor and slotting pawl cause to damage, generally require jack box insert after the completion of install fixed mechanism additional, but
In the case of installation environment complexity, which not only increases the labor intensity of operator, and to assemble
