Description

Split full-insulation power transmission bustar channel device

A kind of separated type all insulation power transmission busbar device belongs to defeated for distribution wiring system technical field.

Before the utility model was made, in prior art, its building need except cable distribution, generally adopt intensive power transmission busbar for the distribution wiring.Power transmission busbar is the rectangle flat copper line, and every alternately wrap with insulation film closed each phase bus then and disturbed and tightly.Shell is a cold-rolled steel sheet, and the four sides is assembled into the rectangle barrel.This structure has the following disadvantages, and 1, heat-sinking capability is poor, consumption copper is big, and because bus is intensive, thermal source is concentrated, and between phase line, phase line is isolated with shell many places insulating material, and heat radiation is difficult, and amount of copper consuming is big; 2, technological requirement height adopts several layer films to isolate between phase line, bus must be smooth, otherwise crush film, forms short circuit; 3, interface place, the phase line bus is all exposed at window, and air-gap is only arranged, and does not have the solid dielectric insulation; 4, steel plate assembly unit shell is perishable, and degree of protection is not high.

The purpose of this utility model is to overcome weak point, thereby provides a kind of cost low, and radiating state is good, the economic current density height, and technology is simple, completely the separated type all insulation power transmission busbar device of equal solid dielectric insulation.

The utility model mainly by barrel (1), plug socket (2), transmission of electricity bus (3), connector (4), link (5), many between link box (6), junction block (8) is formed.Barrel (1) inner chamber has four slotted holes, penetrate the inner chamber of bus (3), connector (4) shell insertion bus barrel (1) in the slotted hole, by inserting transition stem stem (12), be placed with junction block (8) in the connector (4), compress by upper and lower pressing plate (10), (11) of junction block (8).

Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:

The utility model seals barrel (1), garden pipe (or garden bar) shape transmission of electricity bus (3), connector (4), plug socket (2), multidirectional link box (6) formation one bus duct wiring system by engineering plastics.Insulation engineering plastics groove is led (1), inner chamber has four slotted holes, support by long muscle, penetrate garden copper pipe or garden copper bar bus (3) in the slotted hole, groove (copper bar punching two ends) is broken at copper pipe two ends, garden, connector (4) is adopted in the connection of bus duct, and connector (4) shell inserts the inner chamber of bus duct, guarantees the rigidity that barrel is connected.Be placed with many metal connection seats (8) in the connector (4), have upper and lower pressing plate (10), (11) to be conductive copper in the metal connection seat (8).Lower platen (11) is fixed on junction block (8) bottom, is stationary. platen, and top board (10) adopts soket head cap screw (9) to compress, and has copper busbar to pass through between upper and lower pressing plate.The copper busbar method of attachment is performed such: copper busbar one end fluting, insert transition stem stem (12), and stretch in the upper and lower pressing plate of metal connection seat (10), (11) of electric wire connecting junction.Another root copper pipe bus stretches into from the electric wire connecting junction other end, and is inserted in the transition stem stem other end, is in simultaneously between the pressing plate, tightens last 4 soket head cap screws of junction block (8).Pressing plate (10) is pressed on the outer garden of copper busbar, owing to all slot in the bus end, guarantees to have compressed the transition stem stem, has guaranteed the reliable of electric continuity.The grafting of bus is on the bus duct bottom surface, alternately leaves four waist hole windows, and plug socket (2) is housed.Plug socket (2) front is the flat plastic plate that has rectangular window, is cast with the rectangular box of an opening of five face closures of four projectioies on the plate, and rectangular box is inserted in the waist shape window of bus duct bottom surface.The rectangular box side has perforation, and each phase copper busbar is passed from the side, looks from front plug socket rectangular window, and each window only has an exposed bus, is all insulated by solid state medium between exposed bus phase sequence.Bus duct turn to layout, adopt multidirectional link box (6), so that bus duct can intersect the height wiring in the workshop.Multidirectional link box is equipped with link (5).One end of link (5) is connected with bus with the shell of bus duct, and the other end is connected with transition bus (7).The transition bus bends according to turning to requirement, wraps polytetrafluoroethylene film then, or puts the glassfiber insulation pipe, and have insulating barrier to carry out insulating between phase sequence.The transition bus all is placed in the multidirectional link box.The bus duct bus connects identical with above-mentioned method for connecting bus with the transition bus.

Compared with the prior art the utility model has the following advantages: 1, cost is low, and material is economized, and to mould Dai Gang, radiating state is good, the economic current density height; 2, technology is simple, and component models is convenient to install, and is convenient to combination; Since adopted totally-enclosed plastics shell, corrosion-resistant, light, shell protection grade height.
