Description
Technical field
This utility model relates to the diode block of a kind of single-deck rotating rectifier, it is adaptable to low speed low capacity brushless exciter field.
Background technology
Brushless exciter is, by the commutator arranged in rotating shaft, AC rectification is become direct current, provides the electric rotating machine of field power supply for synchronous motor (main frame). Compare with DC exciter, brushless exciter is because eliminating slip ring, brush, will not because of the excessive generation spark of exciting current, solve the problem that in electricity generation system maximization process, required exciting current increases, maintenance is little, the safety of unit also improves accordingly, is widely used to the fields such as water power, boats and ships, nuclear power and aviation at present.
Commutation diode in rotating rectifier is the core component that brushless exciter realizes rectification function, can produce bigger heat in the course of the work. Due to diode heat can not rapidly, effectively cooled medium take away and the accident that causes diode to burn happens occasionally so that brushless synchronous machine needs maintenance down, changes diode element, brings very big loss to factory.
For making the heat of the diode element in rotating rectifier scattering and disappearing efficiently and effectively, a part of product is mounted with that on diode bolt fin is for increasing heat radiation area; Another part product then adds centrifugal fan for air velocity near increasing cooling air delivery and improving. Although cooling effect is good, but former structure is complicated, and difficulty of processing is big, latter increases the axial length of brushless synchronous machine, and the vibrations of unit strengthen.
Summary of the invention
This utility model is intended to provide the diode block of a kind of single-deck rotating rectifier, it is adaptable to low speed low capacity brushless exciter.
The purpose of this utility model is achieved in that
A kind of diode block of single-deck rotating rectifier, its composition includes: diode block (1), it is characterized in that: described diode block (1) is sector structure, centrosymmetry, formed by non-magnet material is aluminum alloy forged, described diode block (1) is provided with screwed hole (2), described screwed hole (2) is used for installing metal-enclosed type commutation diode, described diode block (1) is provided with installing hole (3), by described installing hole (3), diode block (1) utilization is bolted on insulation board, the flat board of described diode block (1) both sides designs for non-constant section, bottom width is 10mm, top width is 8mm, it is highly 50mm.The diode block heat conductivility that this utility model provides is good, and area of dissipation is relatively big, and when rotating with main shaft, near diode, the flow velocity of air is relatively big, is conducive to diode heat loss, extends diode service life.
Beneficial effect:
1. the diode block that this utility model provides adopts good aluminum alloy forged of heat conductivility to form and area of dissipation is bigger; when rotating with main shaft; near diode, the flow velocity of air is bigger; be conducive to diode heat loss, extend diode service life, decrease the diode element because changing overheated scaling loss; unit needs situation about shutting down to occur; and without installing centrifugal fan on main shaft, thus reducing the axial length of unit, the vibrations of unit reduce.
