Description
Technical Field
The utility model relates to a bus duct joint protection device.
Background
Most of the transmission bridges are reserved with long-term interfaces which are actually open ends of bus slots of the upper branch of the bridge trunk. Although the open ends of the bus duct are typically self-contained with a shield that prevents the bus bar ends from being exposed, the shield does not completely enclose the bus bars in the bus duct and does not provide an insulating means to separate the bus bar ends from one another. When the power is on, if sundries are lapped on the bus end, the short circuit of the circuit is caused.
To solve the above-mentioned problems, it is common practice in practical production to use a connector in the prior art to separate and protect bus bar ends, and an utility model specification of chinese patent publication No. CN206595668U discloses a connector of this type. The connector ensures insulation and isolation between adjacent bus duct connectors through the partition plate structures arranged at intervals, but the front end and the rear end of the connector are originally used for butt joint of buses, so that a gap communicated with the outside is necessarily reserved, otherwise, the butt joint function cannot be realized. When the bus duct passes through the instantaneous high-voltage current, the non-closed air gap may cause the high-voltage current to break through the air near the bus head, so that the risk of short circuit still exists. In addition, the connector needs to use the fastener to transversely fasten the bus duct along the arrangement direction when being in butt joint with the bus duct, so that the disassembly and assembly operations are complicated. In addition, the connector includes conductive metal components, so that the cost is high.

The insulating spacer group 10 is formed by stacking insulating spacers 2. The housing 3 in this embodiment is specifically in a hollow rectangular parallelepiped shape, and includes left and right side plates, upper and lower side plates, and a rear side plate.
As shown in fig. 3, the insulating spacer 2 is provided with a recess 8 for fitting the connector of the bus bar groove 1, and the recess 8 in this embodiment is a flat slot formed on the upper and lower sides of the insulating spacer 2 (in other embodiments, only the recess 8 may be formed on the upper or lower side), and opened forward and upward or downward (in other embodiments, the other structure of the recess 8 may be seen in the following). The recesses 8 on adjacent insulating spacers 2 in the insulating spacer group 10 form, in a mating manner, a busbar connection for the insertion of individual busbars in the busbar end 11 and a busbar connection space 9 located directly behind. The rear end of the concave part 8 is closed, and the insulating spacer 2 is provided with a blocking part at the rear of the concave part 8; the plugging parts of the insulating spacers 2 are mutually stacked in the insulating spacer group 10 to form a plugging protection end positioned at the rear end of the shell 3, and the plugging protection end can form an insulating isolation part in front of the joint of the bus duct 1, so that the conditions that high-voltage current breaks down the shell 3 and ionizes outside air are avoided. The insulating spacer group 10 is fixed inside the housing 3 by being pressed by a bolt 7 screwed in through a positioning hole 5 provided on the upper side plate of the housing 3.
The shell 3 is close to the left side plate and the right side plate of the opening and is provided with mounting holes 4 (in other embodiments, the mounting holes 4 can be formed in one of the left side plate and the right side plate), the detachable fixed connection between the shell 3 and the bus duct 1 is realized by screwing a reserved wire hole 6 arranged on the head of the bus duct 1 through the mounting holes 4 through bolts 7, and meanwhile, the upper side plate and the lower side plate, which are close to the bus plug-in port, of the shell 3 are provided with corresponding open slots for forming a notch 13 for observing the inside of the shell 3, and the notch 13 is rectangular. The front ends of the left and right side plates extend forwards and are positioned in front of the bottom of the open slot, and the upper and lower ends of the left and right side plates are bent towards the open slot to form an inward turning edge 12 for reinforcing the strength of the shell 3 near the mounting hole 4. In this way, the forward extending portions of the left and right side plates are reinforced, and the mounting holes 4 are formed in the left and right side plates at positions in front of the bottoms of the open grooves, that is, the extending portions are formed on the extending portions, so that the reinforced extending portions simultaneously reinforce the connecting portions of the mounting holes 4, and the detachable fixed connection structure between the housing 3 and the bus duct 1 is more durable.

In this embodiment, the insulating spacer group 10 is fixed by being blocked by the end of the bus duct 1 on one side and by being pressed by the bolts 7 passing through the positioning holes 5 on the top and bottom surfaces on the other side. The advantage of this mode is that the bolts 7 do not extend into the insulating spacer group 10, and since the bolts 7 are made of metal, the distance from the bus bar end 11 is beneficial for improving the insulating ability. The bolt 7 is fixed on a reserved wire hole 6 reserved at the end part of the bus duct 1 through a mounting hole 4 on the shell 3.
