Description
Technical field
A kind of secondary small bus fitting groove of switchgear of the utility model, belongs to transformer station secondary system security device technology
Field.
Background technique
A large amount of uses of the secondary small bus 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 source 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 significant and is not easy to check.
The fast development of electric system at present also makes the O&M pressure of substation not so that substation's quantity is more and more
Disconnected to aggravate, the DC earthing problem as caused by secondary small bus safe distance deficiency becomes more, especially route enlarging, technological transformation
Become larger etc. the probability for 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 bus is related to is numerous, present position distance is due to successively bus is too close etc., lead
It causes the interval for needing to have a power failure when investigation very much, has aggravated substation's O&M pressure.
Utility model content
The utility model overcomes the shortcomings of the prior art, provides a kind of secondary small bus of fixation, reduces small mother
Line self weight occur bending, reduce between small bus, small bus and regulation between due to safe distance not enough caused by electric discharge, mention
The high small bus stable time the problems such as reducing direct current, be grounded, promotes the small bus assembly of substation secondary O&M level
Slot.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model are as follows: a kind of switchgear is with secondary small mother
Traditional thread binding slot allocation, including small bus, including fixing seat, fixing seat upper surface are provided with the groove of corresponding small bus, small bus setting
In a groove, groove both ends are fixedly installed line card, and groove does not extend through fixing seat both ends, and two end side surface of fixing seat is respectively symmetrically
Multiple secondary string holes are provided with, the secondary string holes at both ends is connected with the line card end of opposite ends by conducting medium respectively, Gu
Cover board is provided with above reservation.
The line card is aluminum line card.
The groove is oblique type groove.
The fixing 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 fastening screw in the fastening thread hole.
The secondary line hole number is 4.
The material of the fixing seat, cover board is isolation material.
The cover board is to be threadedly coupled with the connection type of fixing seat.
The utility model has the advantages that compared with prior art.
1, oblique type groove is set in fixing seat, groove two sides are provided with line card, small bus be disposed therein by line card into
Row is fixed, and increases the stability of small bus, while fixing seat material is isolation material, can be very good to solve small bus with it is small
Interval is fluctuated as caused by various uncertain factors between bus, between small bus and cabinet body, while can solve due to weight
The problem of safe distance of small bus caused by bending caused by power reason and bending and cabinet body shortens, and then alleviate due to above-mentioned
Secondary small busbar grounding problem caused by problem.
2, two end side surface of fixing 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 Yu small bus can be carried out by way of pluggable terminals, it may be implemented
Quickly connection, increases the flexibility, safety and convenience used.
Detailed description of the invention
The utility model is described further with reference to the accompanying drawing.
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram of the utility model groove.
In figure 1 be fixing seat, 2 be line card, 3 be secondary string holes, 4 be small bus, 5 be cover board, 6 be groove, 7 be fastening spiral shell
Pit.
Specific embodiment
As shown in Figure 1 and Figure 2, a kind of switchgear of the utility model secondary small bus fitting groove, including small bus 4, including
Fixing seat 1,1 upper surface of fixing seat are provided with the groove 6 of corresponding small bus 4, and small bus 4 is arranged in groove 6,6 both ends of groove
It is fixedly installed line card 2, groove 6 does not extend through 1 both ends of fixing seat, and 1 liang of end side surface of fixing seat has been symmetrically arranged multiple two
Secondary string holes 3, the secondary string holes 3 at both ends are connected with 2 end of the line card of opposite ends by conducting medium respectively, 1 top of fixing seat
It is provided with cover board 5, line card 2 is aluminum line card, and groove 6 is oblique type groove, and 1 both ends upper surface of fixing seat is located at line card 2 and side
Position be provided with the fastening thread hole 7 of corresponding secondary string holes 3, be provided with fastening screw in the fastening thread hole 7, it is secondary
3 quantity of string holes is 4, and fixing seat 1, the material of cover board 5 are isolation material, and the connection type of cover board 5 and fixing seat 1 is that screw thread connects
It connects.
When the utility model is used, placing one small bus 4 in a groove 6,2 couples of mothers of line card after small bus 4 are placed
Line is fixed stuck, prevents from loosening, secondary line is connected by secondary string holes 3 with line card 2, and then is connected with small bus 4, is made
Used time assembles more small bus 4 using multiple fitting grooves, can between the small bus of effective solution and small bus, small mother
