Embodiment
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
A kind of mounting structure of instrument transformer as shown in Figure 1, described mounting structure comprises instrument transformer 1, instrument transformer support chip 2, partiting thermal insulation sheet 3, sheet metal component 4, first screw association 5, second screw association 6, measured conductor 7(as shown in Figure 2), described instrument transformer 1 and sheet metal component 4 are fixedly connected to form an entirety, the first screw assemblies 5 is used to lock, the quantity of the first described screw assemblies 5 is 4, and model is M5X45; Described sheet metal component 4 and instrument transformer 1 binding face place partiting thermal insulation sheet 3; Measured conductor 7 described is as shown in Figure 2 alignd with the installing hole on it by panel beating location hole, and second group of screw association 6 is fixed on instrument transformer on measured conductor 7, and the quantity of the second described screw assemblies is 4, and model is M5X20.
Described partiting thermal insulation sheet is " U " shape.
Described sheet metal component about 4 respectively has a 4-1 flanging and sheet metal component center hollows out.
Instrument transformer 1 described is as shown in Figure 3 connected and fixed by sheet metal component 4 with measured conductor 7, avoids directly contact and has a gap to be through in the middle of sheet metal component, and this passage dispels the heat to measured conductor surface and instrument transformer as air channel.
Concrete mounting process is as follows:
First instrument transformer 1, instrument transformer support chip 2, partiting thermal insulation sheet 3, sheet metal component 4, first screw association 5 are connected into an entirety.
First support bar 2(2 that instrument transformer is carried) through the little square opening of two on instrument transformer 1, successively partiting thermal insulation sheet 3, sheet metal component 4 are adjacent to the medial surface of current transformer body 1 afterwards, use the first screw association 4(4 again) be arranged in the screwed hole on instrument transformer support bar 2 through the hole on sheet metal component 4, symmetrical fastening for the first screw association 4 successively.
Partiting thermal insulation sheet 3 profile design is U-shaped, and convenient card is fixing on instrument transformer 1.Be stuck on the medial surface of instrument transformer after installing.Partiting thermal insulation sheet 3 is arranged between instrument transformer 1 and sheet metal component 4, can inside instrument transformer 1 binding face side failure of insulation rear protecting, measured conductor 7 adstante febre also can be stoped the thermal radiation of instrument transformer.
Sheet metal component about 4 respectively has a baby hem 4-1 to make position-limiting action when mounted, and the center of sheet metal component 4 hollows out (as shown in Figure 1), is beneficial to and increases instrument transformer binding face and air contact surfaces after center hollows out, and increases heat radiation.
The second screw association 6(4 is used again with measured conductor 2), be connected locking through the through hole on measured conductor 2 with the screwed hole that presses on sheet metal component 5.After locking, sheet metal component 4 is little as much as possible with the contact-making surface of measured conductor 7, to reduce tested leading, and the heat transfer of 7 heatings to sheet metal component 4; Also the contact-making surface both reducing, increases the contact-making surface of conductor and air, is beneficial to heat radiation.
Installation through hole on measured conductor 7 can be designed as several groups, can the installation of compatible various position, and this kind of mounting means also makes the installation site of instrument transformer fix, and technique is easy to control.
Instrument transformer 1 is evenly arranged with employing 4 screws that are fixedly connected with of measured conductor, instrument transformer 1 and measured conductor 2 is connected firmly, uniform force.
In the utility model, the heat dissipation wind channel of instrument transformer is shown in diagram 3.
Wind, from through instrument transformer, to flow through from the surface of measured conductor 7, to outlet.
The air channel of the installation binding face of instrument transformer and measured conductor is up/down perforation, and wind upwards flows through from here from bottom.
The non-installed surface of instrument transformer and measured conductor is hollow.
At the installation binding face of instrument transformer and measured conductor, the center of sheet metal component 4 is empty.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
