Abstract
The utility model relates to an insulation pressure cell, which comprises a ring-shaped cell body with a cavity on the sealed inner side at the bottom; a ring-shaped jacket is arranged in the cavity;a groove is formed by the cavity between the jacket and the cell body; an insulation bearing plate is arranged in the cell body; and a lower pressing block is arranged on the insulation bearing plateand connected with an upper pressing block. Therefore, the insulation pressure cell is adapt to the requirement of high voltage, has the characteristics of high pressure resistant standard and insulation supporting effect, increases the creepage distance, meets the requirement of the present high voltage, and can be extensively applied to various high-capacity rectifying devices to play a role offixing the silicone rectifying tubes.
Description
Technical field
The utility model relates to a kind of insulating pressure box that is used for fixing silicon diode.
Background technology
At present, the big capacity rectifying device voltage of each manufactory's production is more and more higher both at home and abroad, the peak-inverse voltage of silicon diode (thyristor) is increasing, this just requires the insulating pressure box of crimping silicon diode (thyristor) that enough creepage distances are arranged, the insulating pressure box in past does not have groove, the weak point that exists is that creepage distance is little, can not adapt to present high-tension requirement.
Summary of the invention
Its purpose of the utility model just is to provide a kind of insulating pressure box, is used for playing the fixedly effect of rectifying tube between silicon diode (thyristor) and the crimping leaf spring, has the withstand voltage level height, the double again characteristics of doing the insulation support have increased creepage distance, satisfy present high-tension requirement.
The technical scheme that realizes above-mentioned purpose and take is: comprise that bottom lock inside is provided with the annular box body of cavity, be provided with annular chuck in the described cavity, cavity forms groove between chuck and the box body, is provided with the edge backing plate in the described box body, the edge backing plate is provided with lower lock block, and connects upper holder block.
Silicon diode (thyristor) one side is crimped on diplopore copper bar row and goes up another side crimping water-filled radiator, indentation slot type insulating pressure box on the water-filled radiator, put insulating pad in the groove type insulating pressure box and go up lower lock block, putting leaf spring on the upper holder block fixes by screw rod, screw rod leaf spring and diplopore copper bar are idiostatic, it is direct current, and the bottom surface of groove type insulating pressure box is to exchange, so the distance of the bottom surface of the upper holder block of groove type insulating pressure box and groove type insulating pressure box just must be greater than the withstand voltage required creepage distance of alternating current-direct current, this groove type insulating pressure box has increased groove, increased creepage distance, and adopt the expoxy glass resin to make, improved withstand voltage level.
Compared with prior art the utlity model has following advantage:
1, owing to adopted the design of groove type, thereby the withstand voltage level height, doublely again does insulation and support.
2, owing to adopted the design of groove type, thereby increase creepage distance, satisfied present high-tension requirement.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is this apparatus structure front view;
Fig. 2 is Fig. 1 vertical view;
Fig. 3 is the installation diagram of this apparatus structure.
Embodiment
Comprise that bottom lock inside is provided with the annular box body 1 of cavity A, as Fig. 1, shown in 2, A is provided with annular chuck 2 in the described cavity, and cavity forms groove B between chuck 2 and the box body 1, is provided with edge backing plate 5 in the described box body 1, edge backing plate 5 is provided with lower lock block 4, and connects upper holder block 3.
Described box body 1 and chuck 2 are made by the expoxy glass resin.
Silicon diode (thyristor) 7 one sides are crimped on another side crimping water-filled radiator 8 on the diplopore copper bar 6, indentation slot type insulating pressure box 9 on the water-filled radiator 8, put insulating pad 5 in the groove type insulating pressure box 9 and go up lower lock block 3,4, it is fixing by screw rod 11 to put leaf spring 10 on the upper holder block 3, as shown in Figure 3, screw rod 11 leaf springs 10 are idiostatic with the diplopore copper bar, it is direct current, and the bottom surface of groove type insulating pressure box 9 is to exchange, so the upper holder block 3 of groove type insulating pressure box 9 just must be greater than the withstand voltage required creepage distance of alternating current-direct current with the distance of the bottom surface of groove type insulating pressure box 9, this groove type insulating pressure box has increased groove, increased creepage distance, and adopt the expoxy glass resin to make, improved withstand voltage level.
Claims (2)
1, a kind of insulating pressure box, comprise that bottom lock inside is provided with the annular box body (1) of cavity (A), it is characterized in that, be provided with annular chuck (2) in the described cavity (A), cavity forms groove (B) between chuck (2) and the box body (1), be provided with edge backing plate (5) in the described box body (1), edge backing plate (5) is provided with lower lock block (4), and connects upper holder block (3).
2, a kind of insulating pressure box according to claim 1 is characterized in that, described box body (1) and chuck (2) are made by the expoxy glass resin.
