The mode of pin connection will connect axis 2 and fix with operating stick.Simultaneously in the utility model embodiment, connecting card tube 1 is also used for
It inserts and fixes with every section operating stick of insulating bar, riveting also can be used in inserting when fixed or the mode of bolt connection will even
Card cylinder 1 is connect to fix with operating stick.Connection axis 2 and connecting card tube 1 are fixed in operating stick by way of inserting, convenient for fast
Speed realizes the splicing of more piece operating stick, the length of lengthened insulative operating stick.
In the utility model embodiment, connects axis 2 and connecting card tube 1 is hardware.Hardware has resistance to
The stability of the attachment device of insulating bar can be improved in the characteristics of abrasion.
In assembly and connection card cylinder and connection axis, if being provided that backstop groove on the outer wall of connecting card tube, first will
Bayonet lock on connection axis is inserted along sliding slot into connecting card tube, is then rotatablely connected axis, so that the bayonet lock in connection card turns
Cooperate in into backstop groove and with backstop bayonet, connecting card tube can be completed and connects the assembling of axis.If connecting card tube is outer
It is provided that stopper protrusion on wall, the bayonet lock connected on axis is extended into sliding slot first and is inserted into connecting card tube, then rotation connects
Axis is connect, so that in the groove that the inner wall that the bayonet lock on connection axis rotates into stopper protrusion, horizontal protrusion and connecting card tube is formed, i.e.,
The assembling of achievable connecting card tube and connection axis.
On the other hand, the utility model embodiment provides a kind of insulating bar, insulating bar include head and the tail sequentially
Connected at least two operating sticks are detachably connected between at least two operating sticks by attachment device as previously described.
Below by taking the power failure grid switching operation of 110kV substation bus bar maintenance as an example, the connection of insulating bar is filled
The time saving effect set is illustrated, under normal circumstances, when the maintenance of 110kV substation bus bar, need to seal 10 groups of 35kV ground wire,
8 groups of 110kV ground wire.Since operator is when envelope hangs 35kV ground wire, need to increase by 1 section operating stick, when envelope hangs 110kV ground wire,
Need to increase by 2 section insulated lengthened bars.It being calculated according to line three-phase to each group, 1 group of 35kv ground wire of every envelope needs to splice 3 operating sticks,
1 group of 110kv ground wire of every envelope needs to splice 6 operating sticks.Current operating stick is interior male thread structure, is connected through a screw thread,
Outer filament length degree 2.5cm, internal thread length 3.5cm, every connection once-through operation bar needs 0.5 minute, it is consequently possible to calculate going out: every envelope 1
Group 35kv ground line, the time of attended operation bar are as follows: 3 × 0.5 ﹦ 1.5 minutes；1 group of 110kv ground line of every envelope, attended operation bar
Time are as follows: 6 × 0.5 ﹦ 3 minutes.It is possible to calculate: when power failure operation the time of concatenation bar be 10 × 1.5+8 ×
3 ﹦ 39 minutes.Therefore, power failure process concatenation bar needs 39 minutes altogether, extends the grid switching operation time, to also just extend
Power off time, reduces working efficiency.And a kind of attachment device of insulating bar provided by the utility model is grasped in splicing
When making bar, every splicing only needs 4 seconds, by taking the power failure grid switching operation of above-mentioned 110kV substation bus bar maintenance as an example, Ke Yiji
The time for calculating power failure process concatenation bar is only 10.4 minutes.Therefore the utility model can quickly splice more piece operating stick,
The built-up time of insulating bar is saved, splicing efficiency is improved.
The above is only the preferred embodiments of the utility model, are not intended to limit the utility model, all in the utility model
Spirit and principle within, any modification, equivalent replacement, improvement and so on should be included in the protection model of the utility model
Within enclosing.
