Abstract
The invention relates to an anti-vibration connecting device of a transformer for a ship, which relates to the technical field of electrical of the ship. Positioning grooves are symmetrically arranged on the bottom of a transformer base, the top of a connecting piece is embedded inside the positioning groove, two positioning pins which are symmetrically arranged above a shock absorber are matched with two positioning holes which are symmetrically formed on two sides of the connecting piece, a nut sleeves on a bolt, and a gasket is arranged between the nut and the shock absorber. The anti-vibration connecting device is reasonable in structure design, convenient to install, easy to position, good in stability and cable of improving the tightness between the shock absorber and the transformer.
Description
Technical field:
The present invention relates to marine electrical equipment technical field, be specifically related to a kind of damped junction device of marine transformer.
Background technology:
Transformer (Transformer) utilizes mutual inductance principle.Transformer utilizes the principle of electromagnetic induction to change the device of alternating voltage, and main member is primary coil, secondary coil and iron core (magnetic core).Major function has: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilizing (magnetic saturation transformer) etc.
Along with the application of larger-sized vessel and electric propulsion, the change that the transformer situation incidence of ship electric system is very large.In recent years, adopt the boats and ships of ac high-voltage electric device increasing, ship specification advised that the nominal system voltage of boats and ships ac high-voltage device was 3-15kv usually, and illustrated if any special requirement, agrees to, can adopt higher voltage through classification society.Can be used as in power network for power, illumination, isolation equipment; The class of insulation can divide B, F, H level; Marine low-pressure transformer capacity is 2000KVA and following, and electric pressure is below 1KV.Weight peculiar to vessel and ocean platform Satons transformer capacity are 8000KVA and following, and electric pressure is below 10KV.
Vibration absorber (Absorber), concussion when vibration absorber rebounds after being mainly used to suppress spring shock-absorbing and the impact from road surface.Through uneven road surface, although shock-absorbing spring can filter the vibrations on road surface, spring self also has reciprocating motion, and vibration absorber is just used to suppress this spring to jump.Vibration absorber is too soft, and vehicle body will vertical bounce, and vibration absorber will bring too large resistance too firmly, hinders spring normally to work.About in the retrofit process of suspension, hard vibration absorber will be arranged in pairs or groups mutually with hard spring, and the hardness of spring is closely bound up with car weight, and therefore heavier car generally adopts harder vibration absorber.With draw the device shaking bent axle and connect, the torsional shaking of the bent axle that is used for contending with (i.e. the impulsive force of bent axle subject cylinder igniting and twist phenomenon).
Connection in prior art between transformer and vibration absorber is one-point type, poor stability, and not easily locates.
The patent No.: adopt square washer in the marine transformer vibration absorber jockey of 202523537, depth of parallelism during nut screwing clamping can not be ensured, can be stuck after tilt nut, or tighten the instability that can cause between transformer and vibration absorber in an inclined state; Be channel-section steel connected mode in this technology, cannot accurately locate.
Summary of the invention:
The object of this invention is to provide a kind of damped junction device of marine transformer, its reasonable in design, easy for installation, and easily locate, good stability, improve the tightness between vibration absorber and transformer.
In order to solve the problem existing for background technology, the present invention is by the following technical solutions: it comprises transformer base, location notch, connector, location hole, alignment pin, bolt, nut, packing ring, vibration absorber; The bottom symmetrical of transformer base is provided with location notch, the top of connector is embedded in location notch, two alignment pins symmetrical above vibration absorber and monosymmetric two location holes of connector cooperatively interact, and nut sleeve is connected on bolt, is provided with packing ring between nut and vibration absorber.
As preferably, described packing ring is rounded washers, and the intermediate thin of rounded washers, side thickness, uniform force when can ensure nut screwing clamping.
As preferably, described connector is U-shaped structure, improves stability.
As preferably, described packing ring is rubber washer, and packing ring is provided with grip rib, and grip rib contributes to the fastening of nut.
First the top of connector and location notch are inlayed when the present invention installs, by the cooperation of location hole, alignment pin, transformer base and vibration absorber are located again, finally by nut by connector and vibration absorber fastening, the compensator or trimmer pressure that time fastening, packing ring can be strong, make connector and vibration absorber fastening stable.
Beneficial effect of the present invention: its reasonable in design, easy for installation, and easily locate, good stability, improve the tightness between vibration absorber and transformer.
