BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an insulation support block,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an insulation support block, an insulation block unit, and an insulation block assembly using the insulation support block. More particularly, An insulation block unit and an insulation block assembly using the same, wherein the insulation can be selectively assembled in the left and right direction and can be insulated as if the whole bus bar is surrounded, thereby preventing the risk of electric shock due to direct contact with the bus bar will be.

The switchgear is a device that distributes and opens the power supplied from the power plant. It houses the main circuit breaker and monitoring control device in the closed enclosure to prevent the electric shock, so that it can monitor, protect, and operate the power system according to the requirements of the user do. These switchboards vary in the type and size of products according to the rating of the storage equipment, the safety protection class, and the applicable standard.

In the switchboard, a plurality of bus bars are installed to distribute the power supplied from the outside by connecting the respective circuit breakers to each other electrically. In order to reduce the power loss due to the transmission, the bus bars are made of pure copper It is generally manufactured by extrusion molding in a predetermined standard (IEC, JIS, KS).

Properly insulated work is necessary because the surface of the busbar, which is made of pure copper and has excellent electrical conductivity, is left exposed in the air as it presents a high voltage electric shock to workers who repair or inspect the switchboard.

However, in order to prevent the danger of electric shock accident, the insulation work for the installed bus bar should be performed after the power is cut off through the breaker installed in the switchboard. In the case of a large-scale factory equipped with many mechanical devices, There is a problem that an economical loss due to re-operation and a failure of a mechanical device are caused.

Also, in areas that are not adequately insulated, high voltage or unstable power supplied from the transformer may cause strong sparks. At this time, there is a risk that a strong impact is applied to the busbar, resulting in breakage or short-circuiting between busbars.

Therefore, conventionally, a method of covering a bus bar with a heat-shrinkable tube having an insulating function is mainly used for insulation of a bus bar. To accomplish this, a heat-shrinkable tube is inserted into each busbar and heat- I have. Since the insulation using the heat shrinkable tube is completely adhered to the bus bar, it is effective for electrical insulation, waterproofing and protection of devices. However, it has a disadvantage of relatively high cost and low productivity.

Among the prior arts for solving such problems, Korean Utility Model Registration No. 20-0442071, which is a Korean Registered Utility Model No. 20-0442071, is easy to assemble and construct, and the upper and lower fixing bars are detachable so as to support various sizes of the bus bars, The present invention discloses a technique for an insulator support for a bus bar in which a support bar is used as it is, and when a booster bar of another specification is connected, only an upper fixture and a lower fixture corresponding to the specification of the busbar are used.

The prior art described above has the advantage that it can be applied to bus bars of various specifications, but since insulation is provided only at both ends of the bus bar, insulation is not performed except for both ends of the bus bar, As it is.

4 and 5, the insulating support 1 of the present invention is provided on both sides of the bus bar B in the width direction, and the bus bar B is connected to the main plate 110 and the partition wall 120, So that it is separated in an insulated state. Of course, even when the insulating support 1 is fastened to a separate frame provided along the longitudinal direction of the bus bar B, the bus bar B can be separated from the other components of the switchboard 1000 by the insulating support 1 State.

This allows the pair of bus bars B to be connected to the first restricting portion 10 by providing the insulating supports 1 on both sides in the width direction of the bus bar B along the longitudinal direction of the bus bar B. [ It is possible to effectively prevent movement and rotation of each of the bus bars B while separating the pair of bus bars B from the other configurations of the switchboard 1000 in an insulated state There is an advantage to be made.

(Insulation block unit)

The insulating block unit 100 according to the present invention includes a plurality of (three-phase three-wire or three-phase four-wire) bus bars (bus bars) for use in a wiring line, (In a direction opposite to each other) and left and right (in a direction parallel to each other), respectively.

A plurality of such insulating block units 100 are assembled together along the longitudinal direction of the bus bar B to form an insulating block assembly 200 so that the plurality of bus bars B are isolated and accommodated therein.

This is an improvement of the conventional method of covering the bus bar B installed in the wiring line, the distribution board or the like with the use of the heat-shrinkable tube after cutting off the power supply, and the insulating block unit 100 according to the present invention is exposed The assembly can be selectively assembled vertically and horizontally in accordance with the length of the booth bar B installed in the shape of the booth bar B so that it can be insulated as if it surrounds the entire booth bar B, The risk of electric shock due to direct contact with the battery B can be prevented at the source.

In addition, the insulation block unit 100, which is simple and easy to assemble, is modularized in accordance with various installation standards related to the bus bar B, thereby enabling mass production of products for each standard, The insulating work for the bus bar B can be performed more easily, quickly, and safely.

The insulating block unit 100 according to the present invention can prevent the electric shock of the worker due to the contact with the bus bar B and can perform the insulating work of the bus bar B easily, The main plate 110, the partition 120, and the engaging part 130, as shown in FIG.

The insulating support 1, the main plate 110, the partition 120 and the coupling part 130 may be made of synthetic resin, engineering plastic or the like having excellent insulation, heat resistance and rigidity. In particular, Teflon (PTFE, Poly Tetra Fluoroethylene, polychlorotrifluoroethylene (PCTFE), polyvinylidene fluoride (PVDF), polyphenylene sulfide (PPS), polyether ether ketone (PEEK), polyether ether ketone ), MC nylon (Mono Cast Nylon), and the like.

A detailed description of each of the above-described configurations is as follows.

The description of the insulating support 1 will be omitted because the insulating support 1 overlaps with the main plate 110, the partition wall 120 and the coupling part 130 in the following description of the insulating block unit 100 The coupling structure will be mainly described.

The main plate 110 is a component for cutting off contact between the bus bar B and the worker, and is made of a rectangular plate having a predetermined length. The length (long side) of the main plate 110 is determined by taking into account the distance between the phase of the booth bar B and the length of the bus bar B, .

That is, the main plate 110 according to the embodiment of the present invention is formed into a plate shape having a length of at least 39.5 cm (65 mm x 3) on the basis of three-phase three-line, considering that the distance between phases is 65 mm when the nominal voltage is 6600 V For a 3-phase 4-wire system, the length should be at least 46cm (65mm X 4).

The main plate 110 can be manufactured by subdividing the width (short side) so that proper insulation work can be smoothly performed through assembly of the busbars B exposed in various lengths in the lateral direction (direction parallel to each other) .

That is, for example, the width of the main plate 110 can be optionally determined in the range of 2 cm to 20 cm. However, in the embodiment of the present invention, it is possible to secure the convenience and efficiency of assembling work and the stability in the assembled state, and it is possible to make the widths of 10 cm and 5 cm The main plate 110 having a plurality of protrusions is manufactured individually.

In addition, the thickness of the main plate 110 is formed to have a thickness proportional to the magnitude of the large current flowing through the bus bar B, thereby securing the insulating property. However, the embodiment of the present invention forms the main plate 110 with a thickness of about 10T.

On the other hand, at both ends of the main plate 110, an extended fixing part 112 extending outwardly can be formed, and a fastening hole 112A through which the bolt can pass is formed. The insulation block unit 100 according to the present invention can be firmly fixed to one side of the switchgear 10, specifically, the inner frame of the switchgear by means of bolts tightening through the extended fixing part 112 (see FIG. 8).

A reinforcing portion 114 protruding in a concave-convex shape may be formed on the surface of the main plate 110 to increase the bending or torsion strength of the main plate 110.

Further, on the surface of the main plate, a plurality of fixing holes 116 are formed so as to firmly fix the fastening portions in the insulating space S using bolts or the like.

When the insulating block units 100 according to the present invention are assembled facing each other in the up and down direction to form the insulating block assembly 200 as shown in FIG. 4, the barrier ribs 120 are formed between the bus bars B arranged in parallel So that insulation or shielding between the phases is achieved.

The plurality of bus bars B are isolated and accommodated in the insulating block assembly 200 as the partition walls 120 form the insulating space S together with the main plate 110. As each of the bus bars B is isolated and accommodated, a strong spark between the adjacent bus bars B due to the unstable power supply can be prevented, and a strong shock to the bus bar B Breakage and short-circuiting between the bus bars B can be prevented.

The partition part 120 according to the present invention is basically formed at a predetermined interval along the longitudinal direction of the main plate 110. The interval between the partition part 120 and the main plate 110 is determined by the installation type of the bus bar B and the voltage May be formed at various intervals in accordance with the distance between the adjacent booth bars (B).

For example, in the case where the three-phase three-wire bus bars B are installed at intervals of 65 mm, the partition wall 120 is also divided into three parts, that is, 65 mm Four are formed at intervals. In the case of a three-phase four-wire system, the partition part 120 is formed with five pieces at intervals of 65 mm so as to isolate and accommodate four bus bars B by a wall body, respectively, so as to be shielded.

The height (vertical direction) of the partition 120 formed at predetermined intervals along the longitudinal direction of the main plate 110 can be the same as the height, and the height of the partition 120, The first and second barrier ribs 121 and 122 may be alternately formed at predetermined intervals along the longitudinal direction of the main plate 110.

The reason for forming the barrier rib structures having different heights is that when the insulating block units 100 are assembled facing each other in the up-and-down direction and assembled to form the insulating block assembly 200, the assembled and coupled positions are zigzag So that the insulating block unit 100 can not be easily disassembled even if torsional stress or shearing stress acts.

3 to 6, the insulating support 1 is provided between the first partition 121 and the second partition 122 to support the bus bar B in the insulation space S. As shown in FIGS. A pair of fixing holes 116 corresponding to a pair of coupling grooves 30h formed in the coupling portion 30 are formed on the surface of the main plate 110 between the first partition 121 and the second partition 122 Respectively.

4 and 5, the bolts BT are screwed to the coupling grooves 30h through the fixing holes 116 at the outside of the insulating space S, as shown in Fig. 5, the main plate 110 and the fastening portion 30 are in close contact with each other in the insulating space S by the screwing of the bolts BT, So that even if a strong spark is generated in the insulation space S due to high voltage or unstable power supplied from the transformer, damage and safety accidents are prevented.

The first partition 121 according to an embodiment of the present invention has an L height and the second partition 122 has an HL height and is alternately formed along the longitudinal direction of the main plate 110, So that the bus bar B can be accommodated in the insulating space S in the insulating block unit 100.

Particularly, in the case where the bus bar B having a current capacity of about 800 A and having a size of 10 mm X 40 mm is installed at a distance of 65 mm in a three-phase three-wire system, the first and second diaphragms 121 and 121 122 are formed by alternately spacing 65 mm apart from each other to form the insulating block units 100 'and 100 (see FIG. 6).

In the case of a three-phase four-wire system, the first barrier ribs 121 and the second barrier ribs 122 are alternately arranged at a distance of 65 mm. The first barrier ribs 121 are three, the second ribbons 122 Phase four-wire type booth 100 through an assembly of two insulating block units 100, an insulating block unit 100 'consisting of two first partition 121 and three second partition 122, And the bar B, respectively.

5, the first restricting portion 10 and the second restricting portion 20 are prevented from rotating in the insulating space S due to the interference of the partition wall portion 120. As shown in FIG.

The first restricting portion 10 and the second restricting portion 20 are formed in a rectangular parallelepiped shape and the insulating space S is provided in a state where the fastening portion 30 is in tight contact with the main plate 110 by bolt- And a first restricting surface 10f and a second restricting surface 20f which are opposed to the first and second partition walls 121 and 122, respectively.

Therefore, even if any one of the bolts BT forming the coupling force between the coupling part 30 and the main plate 110 is released by an external impact or the like, the first restricting surface 10f of the insulation support 1 And the second restricting surface 20f are interfered by the partition wall portion to maintain the support structure for the bus bar B.

The coupling unit 130 is a component provided to allow the insulating block units 100 according to the present invention to be assembled respectively in the up-and-down direction (the direction facing each other) and the left-right direction (the direction parallel to each other) 132 and lateral coupling means 134, and the like.

The upper coupling means 132 is provided at an upper end of the partition 120 to allow the insulation block units 100 to be vertically assembled in a direction opposite to the other, And an upper coupling groove 132B having a shape capable of fitting the upper coupling protrusion 132A can be formed on the other upper end surface of the upper coupling projection 132A formed on the upper surface.

That is, the upper coupling protrusions 132A and the upper coupling grooves 132B are alternately formed on the upper surface of the partition 120, so that when the insulation block units 100 are assembled in the vertical direction, .

At this time, the upper coupling protrusions 132A may be formed along the upper end surface of the partition 120, but may also be formed in a plurality of protrusions spaced along the upper end surface, And a groove having a shape corresponding to the upper coupling protrusion 132A.

Means that the inner space of the upper coupling groove 132B and the outer shape of the upper coupling protrusion 132A are not physically completely matched with each other but frictional force is generated at the contact surfaces on both sides, Quot; is not applied, it can be understood that the same meaning can be understood as including the case where the clearance is minimized to the extent that it is not easily released.

3 to 7, even when the barrier ribs 120 are formed of the first barrier ribs 121 and the second barrier ribs 122 having different heights from each other, The upper part of the upper part of the first partition 121 is formed with an upper coupling protrusion 132A formed on the upper surface of the first partition 121 and an upper coupling groove 132B formed on the upper surface of the second partition 122 to have an upper coupling protrusion 132A. ).

The side coupling means 134 is provided on at least one side of the main plate 110 and the partition 120 so as to assemble the insulating block units 100 in the lateral direction Or may be formed on one side of one side of the main plate 110 or on one side of the partition 120 or on both sides of both the main plate 110 and the partition 120.

However, the lateral coupling means 134 according to the embodiment of the present invention includes the lateral coupling projections 134A formed along one side of the main plate 110 and the partition 120, And a side coupling groove 134B having a shape in which a pair of side plates 134A can be fitted.

That is, a lateral coupling protrusion 134A and a side coupling groove 134B are formed on both sides of the main plate 110 and the partition 120, respectively, so that the insulation block unit 100 is assembled in the left-right direction When they do, they will fit together in such a way that they fit together.

At this time, due to the structure in which the lateral coupling projections 134A in the longitudinal direction and the lateral direction are fitted to the corresponding lateral coupling grooves 134B in the longitudinal direction and the transverse direction, respectively, 10, it is possible to firmly maintain the bonding force.

The lateral coupling protrusions 134A may be formed along a side surface of the main plate 110 and the partition 120, as well as a plurality of protrusions formed at predetermined intervals along one side of the main plate 110, The groove 134B is formed by a groove having a shape corresponding to this lateral coupling protrusion 134A.

3 through 7, the upper coupling groove 132B formed in the second partition 122, the main plate 110, the partition 120, and the second partition 122 are formed in the same manner as in the embodiment of the present invention shown in FIGS. The side coupling grooves 134B formed on the other side surface are formed in the form of a groove H communicating with each other.

This is because not only the vertical up-down assembly between the upper and lower insulating block units 100 'and 100 but also the upper insulating protrusion 132A' of the upper insulating block unit 100 ' The upper and lower coupling grooves 132B and 134B of the upper and lower coupling grooves 132A and 134B are slidably inserted through the grooves H communicating with each other so as to be assembled and assembled so that the accuracy and convenience of assembly can be dramatically improved (See Fig. 7)

When the insulating block unit 100 is assembled in the vertical direction by the upper coupling means 132 having the protrusions and the grooved structure formed at one end of the insulating block unit 100, The upper insulating block unit 100 'is inhibited from moving in the left direction (in the direction opposite to the Y-axis arrow) by the upper connecting groove 132B and the upper connecting protrusion 132A' of the upper insulating block unit 100 ' (See Fig. 7)

The upper insulating block unit 132A of the lower insulating block unit 100 and the upper insulating block unit 132A of the upper insulating block unit 100 ' (The Y-axis arrow direction) is inhibited from moving (see Fig. 6)

As a result, the insulating block assembly 200 assembled in the vertical direction can be maintained in a firmly assembled state without being detached in the lateral direction.

(Insulation block assembly)

As shown in FIGS. 4 to 7, when the insulating block unit 100 according to the present invention is assembled in the vertical and horizontal directions, the insulating block assembly 200 is formed.

Since the insulating block assembly 200 is accommodated in a state where a plurality of bus bars B are isolated from each other, the insulating block assembly 200 can be prevented from being damaged by direct contact with the bus bar B during work, Risk can be prevented.

The description of the insulating block unit 100 constituting the insulating block assembly 200 is replaced with the above description and the process of assembling the insulating block assembly 200 will be briefly described below with reference to FIGS. do.

First, the insulating block unit 100 is positioned below the bus bar B so that the partition 120 of the insulating block unit 100 protrudes upward.

Next, the upper coupling protrusion 132A 'of the upper insulation block unit 100' for coupling in the up-and-down direction (facing each other) is connected to the upper coupling groove 132B of the lower insulation block unit 100, And the side joint groove 134B are slid to the left side through the groove H communicating with each other (refer to FIG. 7).

When the upper and lower assemblies are formed, the upper and lower coupling ribs 132A and 132B formed on the upper and lower surfaces of the first and second barrier ribs 121 and 122 of the lower insulation block unit 100 The upper insulating block unit 100 'is restrained from moving all the way to the left and right directions (see FIGS. 6 and 7).

More specifically, the upper coupling protrusion 132A 'of the upper insulation block unit 100' is fitted and assembled into the upper coupling groove 132B of the lower insulation block unit 100, And the upper coupling protrusion 132A of the lower insulation block unit 100 is fitted into the upper coupling groove 132B 'of the upper insulation block unit 100' to be moved in the right direction Is suppressed.

Accordingly, when the insulating block assembly 200 is assembled in the vertical direction, the insulating block units 100 are prevented from being separated from each other in the left-right direction, and the assembled state can be firmly maintained.

Next, the side coupling projections 134A of the insulation block unit 100 positioned on the right side fit into the side coupling grooves 134B of the insulating block unit 100 located on the left side for fitting in the left-right direction (See Figs. 6 and 4)

Finally, the assembling is repeated in the up, down, left, and right directions by the length of the plurality of bus bars B exposed to the outside, so that the bus bar B to which a large current flows is separated by the insulating support 1 from the main plate 110, And can be completely insulated from the portion 120. [

On the other hand, since the end portions of the bus bar B are exposed at both end portions of the insulating block assembly 200 in which the opened insulating space S is visible, in order to prevent contact with the end portions of the bus bar B, A sealing plate 300 may be further formed at both ends of the insulating member 200 to allow the insulating space S to be sealed or shielded.

The sealing plate 300 includes a sealing plate 300B formed with a groove 310B corresponding to the side coupling protrusion 134A and a sealing plate 300A formed with a protrusion 310A corresponding to the side fitting groove 134B. Or a single type sealing plate 300 in which grooves corresponding to the side coupling projections 134A are formed on one surface and protrusions corresponding to the side coupling grooves 134B are formed on the other surface.

Fig. 5 shows the front view (Fig. 8) and the side view (Fig. 9) of the insulation block assembly 200 assembled along the path in which the three-phase bus bar B is installed inside the switchboard 10, The bus bar B is not exposed to the outside at all. As a result, an electric shock accident that may occur during operation inside the switchboard 10 can be prevented at the source.
