Abstract
The utility model relates to a rectifying device. The rectifying device comprises a rectifier bridge, an installation plate, a support rod and a direct current busbar. The direct current busbar comprises a positive busbar and a negative busbar. The rectifier bridge is installed on the installation plate. The positive busbar is connected with the positive wire outlet end of the rectifier bridge. The negative busbar is connected with the negative wire outlet end of the rectifier bridge. The support rod comprises a steel screw rod, insulation sleeves and outer layer support sleeves. The steel screw rod goes through the positive busbar and the negative busbar. One end of the steel screw rod is fixed on the installation plate. The other end of the screw rod is compressed through a clamp nut. The insulation sleeve is arranged outside the steel screw rod. The outer layer support sleeves are arranged outside the insulation sleeves between the installation plate and the negative busbar and between the negative busbar and the positive busbar. The Rectifying device uses busbars to connect binding posts of the alternating current side and the direct current side of the rectifier bridge directly and does not use cables with poor heat dissipation performances, and therefore the rectifying device has good heat dissipation performances. Especially, the addition of the support rod solves the weight bearing problem of busbar usage, and the connection of the rectifying device is stable.
Description
Technical field
The utility model relates to a kind of rectifying device.
Background technology
In the DC power supply of existing application, substantially do not re-use DC generator, and mostly adopt alternating current generator, then by rectifying device, be transformed to the mode of direct current.Work in the rectifier of generator high voltage, high electric current environment, in switching process, can produce no small energy loss, be converted to centralized heat energy on rectifier, in order to avoid in rectifier bridge, diode is overheated to be burnt, need utilize fin that heat energy is shed, when output of a generator is higher, the diode of required use is larger, and the required heat energy shedding is more.
At present, the cable that passes through of rectifier unit AC is connected generator with the AC of rectifier bridge, and rectifier unit DC side leading-out terminal is drawn the DC power supply after rectification by cable.The heat that rectifier bridge sheds is passed to cable junction, adds that the loss heat that junction internal resistance brings usually makes cable overheated, adds that cable itself cannot good heat radiating, and too much heat build-up, brings certain potential safety hazard.
Utility model content
The purpose of this utility model is to overcome above defect a kind of heat dispersion good rectification device is provided.
The purpose of this utility model is achieved through the following technical solutions: a kind of rectifying device, it comprises rectifier bridge, mounting panel, support bar, DC master row, described DC side busbar comprises positive busbar and negative busbar, described rectifier bridge is arranged on mounting panel, positive busbar is connected with the positive leading-out terminal of rectifier bridge, negative busbar is connected with the negative leading-out terminal of rectifier bridge, because busbar is heavier, use support bar supplemental support busbar weight, support bar comprises steel screw rod, insulating sleeve, outer supporting sleeve, steel screw rod is through positive busbar and negative busbar, steel screw rod one end is fixed on mounting panel, the other end of steel screw rod compresses by clamp nut, in steel screw rod outside, be provided with insulating sleeve, make to insulate between steel screw rod and busbar, for longitudinal bracing busbar weight, in the insulating sleeve outside between mounting panel and negative busbar and between negative busbar and positive busbar, be provided with outer supporting sleeve.
Preferably, for shock-absorbing, also comprise vibration absorber, vibration absorber one end is arranged on motor, and the other end is connected with the mounting panel of rectifying device.
Preferably, also comprise alternating current bus bar, alternating current bus bar one end connects the AC lead-out wire of motor, and the other end is connected with the AC lead-in wire terminal of rectifying device.
The beneficial effects of the utility model are, because directly using busbar, rectifying device connects the AC of rectifier bridge and the binding post of DC side, do not use the bad cable of heat dispersion, thereby make rectifying device heat radiation good, particularly increased support bar, solved the carrying problem of using busbar weight, made the connection of rectifying device more firm.
