Abstract
A high-temperature resistant ring-shaped insulating plate adopts a ring-shaped plate (1); a plurality of bolt holes (2) of the motor base are formed on the plate; the ring-shaped plate (1) is formed by a plurality of layers of alkali-free glass fiber cloth (3) through compounding; and organic silica gel layers (4) are filled among the alkali-free glass fiber cloth layers. As the insulating plate is formed by layers of alkali-free glass fiber cloth (3) through compounding, and organic silica gel layers are filled among the alkali-free glass fiber cloth layers, the utility model has the advantages that the heat resistance is higher; the insulating plate can stand high temperature within 580 DEG; the insulating property is good; the power frequency dielectric strength is up to 19.8KV/mm; and the mechanical strength is better at the same time, thereby being suitable for the anti-creeping of a circular horizontal motor.
Description
Technical field
The utility model relates to a kind of plate shape that is installed between motor base and the basis and isolates part, a kind of high temperature resistant annular insulation board.
Background technology
In every profession and trade, all kinds of motors are used widely, and on the surface-based cement seat that has, what have is installed on the machine, and what also have is installed on the member that each metalloid material makes.The input voltage of motor belongs to forceful electric power at China normally 380V or 220V.In whole equipment or the whole drive system, motor is that the input of electric current also is the place of the easiest generation electric leakage.In case motor generation electric leakage accident, whole metal and the equipment that links with motor base all will become electrified body, and the electric shock casualty accident takes place easily.Therefore in the demanding drive apparatus of coefficient of safety,, improve the device security performance, cover earth leakage protective device, for example an electronic leakage protector often is installed in equipment in order to prevent the transmission mechanism electric leakage.This earth leakage protective device input cost height, the user of service of equipment and installation personnel should possess certain electrician's knowledge, and Circuits System itself is gone back easy break-down simultaneously.
Summary of the invention
The purpose of this utility model is the structure that proposes the insulation board that a kind of motor base uses, a kind of high temperature resistant annular insulation board, and good insulation preformance has higher thermal endurance, also has mechanical strength preferably simultaneously.
This high temperature resistant annular insulation board is an annular slab, and several motor cabinet bolts hole are arranged on the plate.This annular slab is composited by the multilayer alkali-free glass fiber cloth, is filling the organosilicon glue-line between the alkali-free glass fiber cloth.
This high temperature resistant annular insulation board is owing to be composited with alkali-free glass fiber cloth, and silica filled organopolysiloxane glue-line between the alkali-free glass fiber cloth, thereby good insulation preformance, has higher thermal endurance, also has simultaneously mechanical strength preferably, it is installed under the base of motor, can plays the effect of good electric leakage blocking-up.
Description of drawings
Fig. 1 is the outline drawing of this high temperature resistant annular insulation board;
Fig. 2 is the A-A cutaway view.
Embodiment
As shown in Figure 1, this high temperature resistant annular insulation board is an annular slab 1, and several motor cabinet bolts hole 2 are arranged on the plate.As shown in Figure 2, annular slab 1 is to be composited mutually by multilayer alkali-free glass fiber cloth 3, is filling organosilicon glue-line 4 between the alkali-free glass fiber cloth.
Alkali-free glass fiber cloth and organic silica gel complex that this high temperature resistant annular insulation board is used are full of resistant to elevated temperatures organic silica gel between glass fabric and in the space of glass fabric, have good thermal endurance, can bear 580 ℃ with interior high temperature; Insulation property are also fine, and the power frequency dielectric strength reaches 19.8kv/mm; And have mechanical strength preferably, can carry out machining.This high temperature resistant annular insulation board is installed under the base of motor, can plays the effect of good electric leakage blocking-up.This high temperature resistant annular insulation board is applicable to the installation of circular vertical machine.
Alkali-free glass fiber cloth in this high temperature resistant annular insulation board can adopt the alkali-free glass fiber cloth of medium-coarse, superimposed after evenly coating organic silica gel on the glass fabric, put on the hot press of temperature control, through the pressurization of heating, make sheet material, again with sheet material through machinings such as cutting, turning, borings, make required shape of product.
Claims (1)
1, a kind of high temperature resistant annular insulation board, it is an annular slab (1), several motor cabinet bolts hole (2) are arranged on the plate, it is characterized in that above-mentioned annular slab (1) is to be composited mutually by multilayer alkali-free glass fiber cloth (3), is filling organosilicon glue-line (4) between the alkali-free glass fiber cloth.
