The device has simple structure, is convenient to carry and use, has high insulating strength, and prevents the line from power off andenables operators to safely carry out the electrified operation. The device is an indispensable tool for electrically dividing 10 kV lines and electrically replacing switch blades on closed-end rods.The device enables the electrified operation mode to be flexible and various, has stronger distribution line maintenance planning, and plays the important functions of improving the power supply reliability and the electrical enterprises service image.
Description
Technical field
The utility model relates to a kind of distribution line live working instrument, relates in particular to a kind of drainage jockey of the 10kV of being used for circuit.
Background technology
The raising that requires along with distribution network reliability, need opened and segmented on original circuit, install plug-in strip on the bar of remaining silent additional.Meanwhile, because service time is long, plug-in strip failure and other reasons on the bar, plug-in strip need be changed on a lot of operating bars of remaining silent.
The common ground that the 10kV circuit is opened and segmented to be installed plug-in strip on the bar of remaining silent additional and change plug-in strip on the bar of remaining silent is to need to change the current flowing path.If do not adopt interim drainage measure directly to disconnect alive circuit, can make on the one hand had a power failure by electric side user, more crucial is lead the cut-offs powerful electric current in back can make between two section leads air ionization, produce powerful electric arc, jeopardize operating personnel and power grid security, so above two projects can only have a power failure and carry out, amount when having lost a large amount of power supply reduces power supply reliability.
Summary of the invention
The purpose of this utility model provides a kind of drainage jockey of the 10kV of being used for circuit exactly in order to address the above problem, this device can guarantee uninterrupted power supply, promotes charged job safety coefficient.
The purpose of this utility model is achieved in that
The utility model discloses a kind of drainage jockey of the 10kV of being used for circuit, this device comprises drainage thread and insulator crossarm, and described insulator crossarm is provided with and is used to support the fixedly fixture of drainage thread.
At the above-mentioned drainage jockey that is used for the 10kV circuit, drainage thread is made up of core, the swivel joint that is wrapped in the outer field insulating barrier of core and is located at the drainage thread two ends, and drainage thread does not have external shield.
At the above-mentioned drainage jockey that is used for the 10kV circuit, fixture is provided with groove, and described drainage thread is stuck in the groove of described fixture.
At the above-mentioned drainage jockey that is used for the 10kV circuit, insulator crossarm adopts epoxy resin to make.
The utlity model has following characteristics: the utility model is simple in structure, carries, easy to use, and the dielectric strength height can make circuit not have a power failure and makes the operating personnel can carry out live line working safely.It is charged opened and segmented, the charged for replacement of the 10kV circuit indispensable instrument of plug-in strip on the bar of remaining silent.Adopt the utility model to make the live line working mode more flexible, various, the distribution line maintenance scheduling is stronger, for important effect has been played in the raising of power supply reliability, the lifting of electric power enterprise service image.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of insulator crossarm;
Fig. 3 is the structural representation of drainage thread.
Embodiment
Referring to Fig. 1 to Fig. 3, the utility model drainage jockey comprises drainage thread 2 and insulator crossarm 1.
In above-mentioned drainage jockey, described drainage thread 2 by core 21, be wrapped in the outer field insulating barrier 22 of core and swivel joint 23 3 parts are formed, maximum current capacity is 300A, the insulating barrier voltage endurance capability is 45kV*min.2 two swivel joints 23 of drainage thread reliably are connected with the live wire 3 of cut-off point both sides respectively, and after relevant devices and alive circuit disconnection, electric current does not influence the circuit normal power supply by drainage thread path flow mistake, guarantees personnel, device security.After finishing, construction reverts to the original state of equipment.
In above-mentioned drainage jockey, described insulator crossarm 1 is made by epoxy resin, described insulator crossarm 1 is provided with three and is used to support the fixedly fixture 12 of drainage thread 2, has groove on this fixture 12, and described drainage thread 2 can be fixed in the described groove.During use, insulator crossarm 1 fixedly mounts on the electric poles 4 by fastener 14, and is positioned at live wire 3 downsides, and the 3rd contact point as outside drainage thread 2 and 3 two contact points of live wire plays support, fixation to it.One big advantage of insulator crossarm 1 is exactly that it is formed by the insulating material making, makes drainage thread 2 keep certain space mutually with earth electrode and neighbour.
Above embodiment is only for the usefulness that the utility model is described, but not to restriction of the present utility model, person skilled in the relevant technique, under the situation that does not break away from spirit and scope of the present utility model, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present utility model, should be limited by each claim.
Claims (4)
1. a drainage jockey that is used for the 10kV circuit is characterized in that this device comprises drainage thread and insulator crossarm, and described insulator crossarm is provided with and is used to support the fixedly fixture of drainage thread.
