Description
Technical field
The secondary small busbar fitting groove of switchgear of the present invention, belongs to transformer station secondary system technical field of safety devices.
Background technology
A large amount of uses of the secondary small busbar in relay protection cell, high-voltage switch gear room, make in power supply system in substation
Utility powers, the alternating voltages such as common DC power supply, AC power are arranged in transformer station secondary system in bus type, are made
The direct current of transformer station secondary system, AC system become more convenient outer, also make DC earthing problem, the alternating current of electrical secondary system
Pressure problem with grounding becomes more notable and is not easy to investigate.
The fast development of electric system at present so that substation's quantity is more and more, also makes the O＆M pressure of substation not
Disconnected to aggravate, the DC earthing problem caused by secondary small busbar safe distance deficiency becomes more, especially circuit enlarging, technological transformation
Become larger etc. the probability for making alternating voltage ground connection occur, once there is the problems such as DC earthing, alternating voltage ground connection, easily causes guarantor
Protection unit malfunction, according to dynamic, and since interval that small busbar is related to is numerous, present position distance is due to busbar is too close etc. successively, lead
It causes the interval for needing to have a power failure when investigation very much, has aggravated substation's O＆M pressure.
Invention content
The invention overcomes the deficiencies of the prior art, and provides a kind of secondary small busbar of fixation, reduce small busbar certainly
Reppear existing bending, reduce between small busbar, between small busbar and regulation due to safe distance not enough caused by electric discharge, improve small
Bus run stabilization time promotes the small busbar fitting groove of substation secondary O＆M level the problems such as reducing direct current, be grounded.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is：The secondary small busbar fitting groove of switchgear,
Including small busbar, including fixed seat, fixed seat upper surface is provided with the groove of corresponding small busbar, and small busbar is arranged in a groove,
Groove both ends are fixedly installed line card, and groove does not extend through fixed seat both ends, and two end side surface of fixed seat has been symmetrically arranged more
The secondary string holes of a secondary string holes, both ends is connected with the line card end of opposite ends by conducting medium respectively, above fixed seat
It is provided with cover board.
The line card is aluminum line card.
The groove is oblique type groove.
The fixed seat both ends upper surface is located at the fastening spiral shell that line card is provided with corresponding secondary string holes with the position of side
Pit is provided with trip bolt in the fastening thread hole.
The secondary line hole number is 4.
The material of the fixed seat, cover board is isolation material.
The cover board is to be threadedly coupled with the connection type of fixed seat.
The present invention has the advantages that compared with prior art.
1, oblique type groove is set in fixed seat, groove both sides are provided with line card, small busbar be disposed therein by line card into
Row is fixed, and increases the stability of small busbar, while fixed seat material is isolation material, can be very good to solve small busbar with it is small
It is spaced due to being fluctuated caused by various uncertain factors, while can be solved due to weight between busbar, between small busbar and cabinet
The problem of safe distance of small busbar and cabinet caused by bending caused by power reason and bending shortens, and then alleviate due to above-mentioned
Secondary small busbar grounding problem caused by problem.
2, two end side surface of fixed seat is provided with secondary string holes, and secondary string holes is connected by conductive medium with line card, Ke Yifang
Just realization lines branch, while the connection of secondary line and small busbar can be carried out by way of pluggable terminals, it may be implemented
Quickly connection, increases the flexibility, safety and convenience used.
Description of the drawings
Following further describes the present invention with reference to the drawings.
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is the structural schematic diagram of groove of the present invention.
In figure 1 be fixed seat, 2 be line card, 3 be secondary string holes, 4 be small busbar, 5 be cover board, 6 be groove, 7 be fastening spiral shell
Pit.
Specific implementation mode
As shown in Figure 1 and Figure 2, switchgear of the present invention secondary small busbar fitting groove, including small busbar 4, including fixed seat 1,
1 upper surface of fixed seat is provided with the groove 6 of corresponding small busbar 4, and small busbar 4 is arranged in groove 6, the fixed setting of 6 both ends of groove
There are line card 2, groove 6 not to extend through 1 both ends of fixed seat, 1 liang of end side surface of fixed seat has been symmetrically arranged multiple secondary string holes 3,
The secondary string holes 3 at both ends is connected with 2 end of the line card of opposite ends by conducting medium respectively, and 1 top of fixed seat is provided with lid
Plate 5, line card 2 are aluminum line card, and groove 6 is oblique type groove, and 1 both ends upper surface of fixed seat is located at line card 2 and the position of side is set
It is equipped with the fastening thread hole 7 of corresponding secondary string holes 3, trip bolt is provided in the fastening thread hole 7, secondary string holes 3 counts
Amount is 4, and fixed seat 1, the material of cover board 5 are isolation material, and cover board 5 is to be threadedly coupled with the connection type of fixed seat 1.
In the use of the present invention, place a small busbar 4 in a groove 6, place after small busbar 4 line card 2 to busbar into
Row fixation is stuck, prevents from loosening, secondary line is connected by secondary string holes 3 with line card 2, and then with small busbar 4 is connected, when in use
More small busbares 4 are assembled using multiple fitting grooves, can between the small busbar of effective solution and small busbar, small busbar with
It interval between cabinet, can be with the secondary small busbar grounding of effective solution due to the influence fluctuated caused by various uncertain factors
The problem of, the quick connection between secondary string holes and secondary line can be fastened by fastening thread, prevent connection from loosening,
