According to actual detection data and simulation analysis results, the junction box and the unit can resonate, the vibration amplitude level exceeds an allowable value, and related connecting parts can be subjected to wire fatigue fracture in the long-term use process. Aiming at the problems and the defects, a vibration reduction structure of the junction box needs to be designed, and the vibration level of the junction box is greatly reduced to a qualified level.
Disclosure of Invention
The utility model aims to solve the technical problem that a generator junction box damping structure of low vibration range is provided, can reduce junction box vibration level by a wide margin, solve the resonance problem of junction box.
In order to solve the technical problem, the technical scheme of the utility model is that: the utility model provides a generator junction box damping structure of low vibration range, is including establishing the joint strip in junction box end plate bottom, establishing rubber damping pad and the terminal box support on the generator frame, the one end of terminal box support is fixed on the rubber damping pad, the other end and the terminal box end plate of terminal box support are connected, joint strip and generator frame contact. The utility model discloses in the structure, the rubber damping pad passes through the terminal box support and supports the terminal box, and joint strip and generator frame contact are passed through to the end plate bottom of terminal box, and whole terminal box does not contact with the generator frame, can reduce the vibration range of terminal box effectively, eliminates resonance.
As an improvement, the sealing rubber strip is provided with an embedded groove, and the lower end of the terminal box body end plate of the junction box is arranged in the embedded groove of the sealing rubber strip.
As an improvement, the junction box support is L-shaped and comprises a horizontal mounting plate and a vertical mounting plate, and the horizontal mounting plate and the rubber vibration damping pad are fixed on the generator base through a first bolt.
As an improvement, the vertical mounting plate is tightly attached to the end plate of the junction box body, and the vertical mounting plate and the end plate of the junction box body are connected through a second bolt.
Compared with the prior art, the utility model the beneficial effect who brings is:
the rubber vibration damping pad supports the junction box body through the junction box support, the bottom of the end plate of the junction box body is in contact with the generator base through the sealing rubber strip, and the whole junction box body is not in contact with the generator base, so that the vibration amplitude of the junction box body can be effectively reduced, and resonance is eliminated.
