Abstract
The invention provides a trap-typed capacitor fixing device, consisting of an electrolytic capacitor, an upper capacitor fixing plate, a lower capacitor fixing plate and a fixing support frame. The fixing support frame is arranged at the left and right ends of the upper capacitor fixing plate and the lower capacitor fixing plate. The fixing support frame takes the shape of 'I' and is fixed by bolts. Six to twelve grooves are processed on the internal surface of the upper capacitor fixing plate and are distributed in two rows at intervals. Two layers of counterbores are processed on the lower capacitor fixing plate at the positions corresponding to the grooves of the upper capacitor fixing plate. The terminal of the electrolytic capacitor faces the counterbores of the lower capacitor fixing plate while the other end stretches into the grooves of the upper capacitor fixing plate. The device fastens the capacitor module and facilitates modularized mounting and demounting. The device has excellent insulativity. The device adopts an integral design, wherein, fixing, mounting and wiring of the capacitor are integrated. The device is applicable for the fields of rail vehicle, light rail,subway, Maglev train, industrial converter, etc.
Description
Technical field
The present invention relates to the fixture of capacitor.
Background technology
Adopt the current transformer power supply product of power electronic technology development to be widely used in every field such as electric power, military project, industry, commerce, agricultural, only all trades and professions that promptly spread all over the world of frequency converter at present.Along with the improving constantly and develop of power electronics application technology, more and more embody each side advantages such as current transformer energy-saving and environmental protection, and obtained user's extensive approval.
Because its vast market space and social demand, current transformer is also developing towards little, the capacious direction of volume rapidly, core on the cabinet body structure is exactly a power cell, and direct voltage to support fixing, the installation and the wiring problem of capacitor be one of most significant problems of current transformer power cell electrical structure.
Direct voltage supports capacitor and is generally electrolytic capacitor, and the conventional fixed mode is to adopt electric capacity to fasten on casing or cabinet.Inconvenient installation and removal of such mounting means, and volume required space is bigger are not suitable for that power is done greatly, the current transformer development trend of size decreases; This mode capacitor of also grinding away easily leaks electricity, danger such as short circuit easily, in order to remedy this shortcoming, needs to fill up rubber sometimes and carries out abrasionproof and handle, and has increased the inconvenience of installing again.At existing problem in the above-mentioned prior art, a kind of novel trap type capacitor fixing device of research and design, existing problem is very necessary in the prior art thereby overcome.
Summary of the invention
In view of existing problem in the above-mentioned prior art, the objective of the invention is a kind of novel trap type capacitor fixing device of research and design, thus solve the inconvenient installation and removal of electrolytic capacitor, take up room greatly, the capacitor of easily grinding away, leak electricity easily, problem such as short circuit risk.Trap type capacitor fixing device of the present invention is made up of electrolytic capacitor, capacitor fixing upper plate, capacitor fixing lower plate, fixed support.Fixed support is equipped with at the two ends, the left and right sides of capacitor fixing upper plate and capacitor fixing lower plate, and fixed support is " worker " font, by screw; 6-12 groove of inner face processing of described capacitor fixing upper plate divides two rows to equidistantly distribute.On the capacitor fixing lower plate, be processed into the two-layer stepped hole corresponding with capacitor fixing upper plate groove location.The terminals of electrolytic capacitor are towards the stepped hole of capacitor fixing lower plate, and the other end stretches in the groove of capacitor fixing upper plate.Capacitor fixing upper plate of the present invention, capacitor fixing lower plate are selected epoxy resin board processing for use; Fixed support selects for use phenolic resin material to carry out the mould compression process.Doing dipping lacquer after capacitor fixing upper plate of the present invention, the capacitor fixing lower plate completion of processing handles.
The objective of the invention is to develop a kind of direct voltage and support capacitor fixing device for current transformer, this device changes the capacitor fixed form of electric capacity cassette in the past, adopt trap type capacitor fixing device to embed, push, surround electric capacity fixing fully, realize the modularized design of main circuit power cell easily, electric convenient with mechanical interface, be convenient to the modularization installation and removal.This device is applicable to that with IGBT or IGCT its range of application can relate to numerous areas such as railway locomotive, light rail electrical car, subway, magnetic suspension train, industrial frequency transformer in the rectification or inversion cabinet body structure as the master power switch element.
Advantage of the present invention mainly shows and has changed the inconvenience that original capacitor adopts the installation and removal of electric capacity cassette, makes capacitance module more fastening, has strengthened the shock resistance of capacitance module, and has made things convenient for the modularization installation and removal; Make the smaller volume of capacitance module simultaneously, make current transformer casing or cabinet body structure compact more, help the optimization of electric property; Adopt insulation device fixed capacitor, the ground short circuit fault can not take place, thereby strengthen its fail safe in the capacitor of can not grinding away when the electric capacity fault; Adopt integrated design, fixing, installation, the wiring of current collection container are one.Industry and civilian field of power supplies be can be widely used in, railway locomotive, light rail electrical car, subway, magnetic suspension train, industrial frequency transformer etc. are applicable to.
