Abstract

The present utility model discloses a line bank with stationary contacts. The line bank comprises an insulating crossbeam and three terminals. Three bulges are arranged side by side on the same side of the insulating crossbeam, each bulge is provided with a vertical through-hole, and a horizontal through-hole with the axis of which running through the vertical through-hole is also arranged on each bulge. The middle part of each terminal is provided with a horizontal through-hole, the upper part of each terminal is provided with a through-hole for connecting with a bus, and the lower part of each terminal is provided with a stationary contact. The three terminals respectively run through the vertical through-holes of the bulges of the insulating crossbeam, and the terminals are fixed on the bulges of the insulating crossbeam by passing a bolt through the horizontal through-holes of the bulges of the insulating crossbeam and the horizontal through-holes of the middle parts of the terminals. The bulges can be designed as mountain-shaped bulges, and a spacing flat surface can be arranged on the side surface contacting part of the lower part of each bulge and the lower part of each terminal. The line bank is compact in structure, can effectively reduce the volume of an isolation switch, is convenient to assemble, and has good insulation effects.

Description

The line bank of band fixed contact

Technical field

The utility model relates to the power disconnecting switch equipment technical field, the line bank of the band fixed contact that especially a kind of isolating switch is used.

Background technology

In the three-phase isolation switch equipment of electric power system, need a line bank with the inlet highway junction, binding post one end in the line bank will be connected with inlet highway, the other end will cooperate as the disconnecting link of fixed contact and isolating switch, traditional way is to utilize three insulators, three binding posts are fixed on the insulator, and then three insulators that have a binding post are installed to form a three-phase line bank on the support, at last install on the housing of isolating switch more together, this by insulator, binding post, prop up the line bank volume that is configured to and make that more greatly the volume of whole isolated switch is also bigger, also inconvenience is installed, and insulation effect is relatively poor.

The utility model content

The technical problems to be solved in the utility model provides a kind of line bank with fixed contact, and its compact conformation can effectively reduce the volume of isolating switch, and easy for installation, insulation effect is good.

For achieving the above object, the technical solution of the utility model is: a kind of line bank with fixed contact, comprise that one thoroughly does away with the edge crossbeam, three binding posts, there are three projectioies side by side the same side of insulation crossbeam, described projection all has a vertical through holes, described projection also has an axis to run through the cross through hole of described vertical through holes, there is a cross through hole at each binding post middle part, the through hole that is connected with bus is left on each binding post top, each binding post bottom is a fixed contact, three binding posts pass the vertical through holes of insulation crossbeam projection separately, and the cross through hole and the cross through hole in the middle part of the binding post that are passed insulation crossbeam projection by bolt are fixed on insulation crossbeam high spot to binding post.

Further, described projection is the projection of chevron, makes bulk strength better.

In described protruding bottom and binding post lower side contact position a spacing plane 113 is set, has guaranteed that the disconnecting link fast rotational does not misplace to the fixed contact cooperation.

Be provided with on described each binding post top one with the perpendicular connecting plate of main body, the through hole that is connected with bus is arranged on the place, diagonal angle of connecting plate, conveniently overlaps mutually with inlet highway, contact-making surface is bigger.

Two ends at described insulation crossbeam are embedded with nut, make whole line bank easier for installation on the isolating switch housing.

Two ends at described insulation crossbeam are provided with positioning convex, make whole line bank and isolating switch housing locate faster mutually.

The utility model insulation crossbeam is worked as the support of binding post again both when the insulator of binding post, so compact conformation, and volume is little, is contained in the volume that can effectively reduce the whole isolated switch on the isolating switch.

Binding post passes the vertical through holes of insulation crossbeam projection, the cross through hole and the cross through hole in the middle part of the binding post that pass insulation crossbeam projection with bolt just can be fixed on insulation crossbeam high spot to binding post, install simple, the two ends of whole line bank utilization insulation crossbeam are embedded with nut and normal screws just can fix with isolating switch, install easily, the insulation crossbeam is also better than other support insulation effect.

Embodiment

Below in conjunction with accompanying drawing and concrete execution mode the utility model is described in further detail.

Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, a kind of line bank with fixed contact, comprise that one thoroughly does away with edge crossbeam 1, three binding posts 2, there are three projectioies 11 side by side the same side of insulation crossbeam 1, described protruding 11 all have a vertical through holes 111, described protruding 11 also have an axis to run through the cross through hole 112 of described vertical through holes 111, there is a cross through hole 21 at each binding post 2 middle part, the through hole 22 that is connected with bus is left on each binding post 2 top, each binding post 2 bottom is a fixed contact, shape matches with the disconnecting link that will be connected, three binding posts 2 pass the vertical through holes 111 of insulation crossbeam 1 projection 11 separately, and the cross through hole 21 that passes the cross through hole 112 of insulation crossbeam 1 projection 11 and binding post 2 middle parts by bolt 3 is fixed on binding post 2 at projection 11 places of the crossbeam 1 that insulate.

Described protruding 11 can be designed to the projection of chevron.

A spacing plane 113 can be designed in described protruding 11 bottoms and binding post 2 lower side contact positions, makes things convenient for binding post 2 bottoms to engage the position of restriction disconnecting link with the disconnecting link of isolating switch.

Described each binding post 2 top have one with the perpendicular connecting plate 23 of main body, the through hole 22 that is connected with bus is arranged on the place, diagonal angle of connecting plate 23.

The two ends of described insulation crossbeam 1 are embedded with nut 4.

The two ends of described insulation crossbeam 1 are provided with positioning convex 12.

When the utility model uses, can utilize the two ends of insulation crossbeam to be fixed on the framework upper of isolating switch, the binding post upper end is connected with inlet highway, matches with the disconnecting link of isolating switch as fixed contact in the bottom of binding post.

The utility model also can be arranged on the framework bottom of isolating switch; corresponding binding post shape reaches and the position of bus connecting hole also can change; the quantity changeable of described projection and binding post, the change that those skilled in the art does to be equal to by claim all falls into the protection range of this case.
