Problems solved by technology

Regarding the current situation of cable hole sealing, there are the following problems: (1) If the cable hole is small, it is generally sealed directly with fireproof mud, but as the operation time increases, the fireproof mud is easy to sag and sink when the temperature is high in summer, and it is easy to sink when the temperature is low in winter. It is easy to harden and fall off, and the construction process lacks a unified standard, resulting in the sealing of the cable hole is not tight, and there are great safety hazards in terms of fire prevention and small animal prevention.
After the cement is solidified, it looks firm and firm on the surface, but it actually brings great inconvenience to the follow-up operation and maintenance work
When new cables are installed, it is necessary to demolish the fixed concrete, which is very easy to accidentally damage the cables, causing primary and secondary equipment failures or other accidents, and bringing great safety hazards to the reliable operation of the power grid.

Embodiment 1

[0028] Example 1: A universal adjustable cable hole plugging device for substations (see Figure 1-Figure 6 ), which includes two Z-shaped universal chassis 1, each Z-shaped universal chassis 1 is provided with fixing screw holes 12 and connecting rod connecting screw holes 14, and both ends of each Z-shaped universal chassis 1 pass through The screws 13 are symmetrically connected to the chute devices 2. Each chute device 2 is composed of a fixed introduction groove 9 and the moving guide rails 8 on both sides of the fixed introduction groove 9. The ends of the fixed introduction grooves 9 of the two chute devices 2 The head is symmetrically provided with an elastic limiting plug 11 . The two Z-shaped universal chassis 1 are symmetrically connected with two edge distance adjustment links 4 through connecting rod connection screw holes 14 , and the edge distance adjustment link 4 is formed by connecting two connecting rods through a coupling shaft 3 . The two Z-shaped univers...

Embodiment 2

[0029] Example 2: A universal adjustable cable plugging device for substations (see figure 2 , image 3 , Figure 4 , Image 6 , Figure 7 , Figure 8 ), the structure and principle are basically the same as those of the first embodiment, the difference is that one side of the fire blocking board 5 is provided with a corrugated secondary cable penetration hole 7 .

[0030] When the present invention is used, the Z-shaped universal chassis 1 is adjusted according to the actual cable hole size, and the width of the Z-shaped universal chassis 1 can be adjusted within the width range of 0-600 mm by manually stretching or extruding the margin adjustment link 4, which reflects out the adjustable features of the device. Use a utility knife to drill the fire blocking plate 5 into a primary cable penetration hole 6 or a secondary cable penetration hole 7 according to the actual cable diameter. The slideway 10 of the fireproof blocking board 5 is engaged and pushed along the slid...

Abstract

The invention discloses a general adjustable cable hole blocking device for a transformer substation. The device comprises two Z-shaped general underframes (1), wherein sliding chute devices (2) are symmetrically connected to two ends of each Z-shaped general underframe (1), each sliding chute device (2) is formed by integrally connecting a fixing guide-in groove (9) provided with an elastic limiting plug (11) at one end with movable guide rails (8), two edge distance adjusting link rods (4) are connected between the Z-shaped general underframes (1), mutually symmetrical fireproofing blocking boards (5) are arranged between the sliding chute devices (2), one cable penetrating hole is formed in one side of each fireproofing blocking board (5), the rest three sides are hooped with aluminum alloys, two side edges are connected with slides (10), and the slides (10) are inserted into the movable guide rails (8). The general adjustable cable hole blocking device is convenient to mount and dismount, fireproof, moisture-proof, good in sealing property, long in service life, safe and reliable and guarantees safe and stable operation of equipment.

Description

[0001] Technical field: [0002] The invention relates to a universal adjustable cable hole plugging device for a substation, which belongs to the field of power system transformation operation. [0003] Background technique: [0004] Due to the advantages of small insulation distance between lines and small footprint, cable lines are widely used as primary and secondary input and output lines of substations. When the cables are installed in the station, they usually need to pass through walls or floors. For this reason, special cable holes are required for cable entry and exit. Regarding the current situation of plugging cable holes, there are the following problems: (1) If the cable holes are small, fireproof mud is generally used for direct plugging, but with the increase of operating time, the fireproof mud is easy to sag and sink at high temperature in summer, and low temperature in winter. It is easy to harden and fall off, and the lack of uniform standards for the const...
