Abstract
The utility model discloses an anti-explosion variable-frequency governor used on a narrow-gauge traction anti-explosion electric locomotive. A copper flange is arranged on a flange behind an anti-explosion variable-frequency governor box body, an aluminum plate with a radiating ridge is arranged on the copper flange, and a stainless steel wire screen is assembled on the aluminum plate with the radiating ridge. The anti-explosion variable-frequency governor has the advantages of being capable of meeting requirements of an anti-explosion structure by adopting the aluminum plate with the radiating ridge as a radiating structural member, being capable of meeting requirements of hydrostatic tests of anti-explosion products and being capable of meeting requirements for radiating and enabling a large-power module in the anti-explosion variable-frequency governor not to exceed a limiting temperature during work.
Description
Technical field
The utility model relates to a kind of explosion-proof variable frequency variable speed device.
Background technology
The radiator structure spare that present industrial and mineral narrow gauge draws the explosion-proof variable frequency variable speed device of using in the explosion-proof electric locomotive adopts brass sheet usually; High-power the touching in the heat ambient air that piece sends that makes the explosion-proof variable frequency variable speed device with brass sheet distributes, and guarantees the high-power temperature that do not go beyond the limit of when touching piece work; But the brass sheet expensive, so the manufacturing cost of explosion-proof variable frequency variable speed device is high, and do not have the heat radiation ridge, radiating effect is bad.
The utility model content
The purpose of the utility model provides a kind of aluminium sheet with the heat radiation ridge and draws the explosion-proof variable frequency variable speed device of using in the explosion-proof electric locomotive as the narrow gauge of radiator structure.
The technical scheme of the utility model is; A kind of narrow gauge draws the explosion-proof variable frequency variable speed device of using in the explosion-proof electric locomotive; On the explosion-proof change speed regulator casing rear flange copper flange is housed, the aluminium sheet of band heat radiation ridge is housed on copper flange, at the equipped stainless steel wire guard of aluminium sheet of band heat radiation ridge.
Copper flange is contained on the rear flange through fastening bolt with the aluminium sheet of band heat radiation ridge.
The stainless steel wire guard is bolted on the aluminium sheet of band heat radiation ridge through guard.
The utlity model has following technique effect, 1, adopt the aluminium sheet of band heat radiation ridge to want to satisfy the requirement of blast resistance construction as the radiator structure spare of explosion-proof variable frequency variable speed device; 2, can satisfy the requirement of the anti-explosion product hydraulic test; 3, can satisfy the heat radiation requirement of explosion-proof variable frequency variable speed device, make high-power the touching in the explosion-proof variable frequency variable speed device not go beyond the limit of temperature when piece is worked.
