Specific embodiment
The technical solution of the utility model, but the protection scope of the utility model are described in further detail with reference to the accompanying drawing
It is not limited to as described below.
As shown in Figure 1, a kind of double-T insulated connecting device for the installation of subway DC cabinet, including insulation board 1 and several
Insulate support 2.As shown in Fig. 2, the insulation support 2 includes screw rod 21, nut 22, nut protective cap 24 and two T shape insulation
Part 23.The T shape insulating part 23 is that part is integrally formed made of isolation material, by 231 two parts structure of insulation sleeve 232 and insulating disc
At one end of insulation sleeve 232 is vertically arranged and is fixedly connected with the disk of insulating disc 231, so that the axial direction of the T shape insulating part 23
Section is in T shape.
The T shape insulated connecting device is for the insulating mounting between the cabinet body and basic channel steel of subway DC cabinet, installation
Structure is as shown in Figure 3.When it is implemented, being laid with insulation board 1 on pre-buried channel steel 3, the DC cabinet of subway is mounted on insulation board 1
On.To the one trip-out mounting hole of three-decker that direct current cabinet floor 4, insulation board 1 and pre-buried channel steel 3 are constituted, and respectively from mounting hole
Both ends insertion T shape insulating part 23 insulation sleeve 232, and make the insulating discs 231 of two T shape insulating parts 23 respectively with DC cabinet
Bottom plate 4 and pre-buried channel steel 3 are in contact.Thereafter, screw rod 21 sequentially passes through two T shape insulating parts 23 from the side of pre-buried channel steel 3, and
In its traversing through end attaching nut 22.Two insulating discs 231 may make mutually to draw close by turning nut 22, until making DC cabinet
The connection of bottom plate 4, insulation board 1 and pre-buried channel steel 3 fastens.
Further, the end that screw rod 21 stretches out direct current cabinet floor 4 is provided with nut protective cap made of isolation material
24.The upper portion insulating of the nut protective cap 24 is closed, lower ending opening, and nut 22 is embedded in the lower part for being set to the nut protective cap,
And the lower end of nut protective cap 24 is contacted with its similar insulating disc 231.
Further, insulation board 1 selects SMC composite material to be made, and the material is mainly by special yarn, filler and various auxiliary agents
Composition has excellent electrical insulation capability, mechanical performance, thermal stability and chemically-resistant anti-corrosive properties, compared to the asphalt mixtures modified by epoxy resin with routine
The insulation board of rouge or polycarbonate material, insulation effect is more preferable, and the service life is longer.
Further, high-intensitive insulating cement is coated between above-mentioned each contact site and two insulation sleeves 232.
By above-mentioned setting, protected between direct current cabinet floor 4 and pre-buried channel steel 3 by insulation board 1, T shape insulating part 23, nut
Cap and insulating cement is completely insulated separates, so that its connection can reach more insulation effect.In addition, more DC cabinets side by side
When installation, it can be selected and cover the insulated connecting device more, installed using the method that the fissure of displacement is installed.During installation, so that it is adjacent
The gap position between gap and two neighboring insulation board 1 between two direct current cabinet floors 4 is staggered, and at above-mentioned gap into
Row grinding process and with insulation glue bond, mounting structure as shown in Figure 3 is installed thereafter.It is insulated and is connected by the double-T
The DC equipment of device installation, insulation values are greater than 40M Ω through measurement, and much higher than the insulating requirements of 1M Ω, insulation effect is good
It is good, it is ensured that the safe and smooth operation of city rail.
To realize batch making, production cost is reduced, above-mentioned T shape insulating part 23 is usually unified production, specification
It is identical.But the size in actual use, needing to control insulation sleeve 232 avoids its too long and causes the company of DC cabinet and channel steel
Connect defective tightness, this to be installed between latter two insulation sleeve 232 there are gap, by being used for a long time, some dust and
Metal micro particles enter at the gap, will lead to insulation effect decline.Therefore it is preferred, as shown in figure 4, two T shape insulating parts
Specification is not identical, is respectively T shape insulating part a and T shape insulating part b.T shape insulating part a includes the insulation that end is fixedly connected
It covers a233 and insulating disc 231, T shape insulating part b includes the insulation sleeve b234 and insulating disc 231 that end is fixedly connected, insulation sleeve
The diameter of b234 is less than the diameter of insulation sleeve a233.During installation, insulation sleeve b234 insertion is set in insulation sleeve a233, and
Sealing ring 235 is provided between the outer wall of insulation sleeve b234 and the inner wall of the insulation sleeve a233.It is completely eliminated by the setting
Gap between insulation sleeve a233 and insulation sleeve b234 avoids that the case where causing decreasing insulating generation is used for a long time.
Preferably, spring washer 7 and two plain cushions 6 are arranged on screw rod 21, between pre-buried channel steel 3 and an insulating disc 231
And it is provided with insulation spacer 5 between direct current cabinet floor 4 and another insulating disc 231, it can be when tightening nut 22, it is ensured that two
A insulating disc 231 is by 3 clamping fastener of direct current cabinet floor 4, insulation board 1 and pre-buried channel steel between it, while the setting of spring washer 7 is also
Has the ability of the loosening of placing nut 22, so that direct current cabinet floor 4 and pre-buried channel steel 3 are steady by the connection of the insulated connecting device
It is fixed reliable.
The above is only the preferred embodiment of the utility model, it should be understood that the utility model is not limited to herein
Disclosed form, should not be regarded as an exclusion of other examples, and can be used for other combinations, modifications, and environments, and
Can be in contemplated scope described herein, modifications can be made through the above teachings or related fields of technology or knowledge.And this field
The modifications and changes that personnel are carried out do not depart from the spirit and scope of the utility model, then all should be in right appended by the utility model
It is required that protection scope in.
