Abstract
The utility model relates to a frequency converter suitable for a multi-vibration working environment. The frequency converter comprises at least one group of capacitors, wherein each group comprises six capacitors; and the top of each group of capacitors is fixed with a metal fixed pressure plate through a rubber pad. The frequency converter has the beneficial effects that: high anti-vibration property is achieved, and the reliability of the frequency converter in a multi-vibration severe working environment is ensured.
Description
Technical field
The utility model relates to a kind of frequency converter, relates in particular to the mounting structure of electric capacity in this frequency converter.
Background technology
Frequency converter is being brought into play its crucial effects in the utilization of industry-by-industry at present, and having arrived can't substituted status.Frequency converter can accurately be controlled mechanical movement, improves the accuracy of technology and the high efficiency of operation widely.
Usually frequency converter can carry out work well in good working environment, but under the environment of certain adverse, Inverter Application can be restricted.Such as in the application of coal mine machinery, frequency converter and variable-frequency motor all are installed in the coal-winning machine.Coal-winning machine is in operation, and the big and small cinder that drops on the operation track often makes job platform produce vibration, and especially coal-cutting machinery more can produce violent vibration when excavating rock.Under the effect, the wiring pin of the electric capacity that frequency converter is inner is easy to cause that solder joint is loosening even fatigue failure takes place in gravity and this vibration.
Summary of the invention
The utility model technical issues that need to address have provided the reliable frequency converter of electric capacity mounting structure, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is realized through following technical scheme:
The utility model comprises: at least one group of electric capacity; Every group is 6 electric capacity; The top of every group electric capacity is fixed through a rubber blanket and metal fixation clip.
Compared with prior art, the beneficial effect of the utility model is: have stronger freedom from vibration, guaranteed the reliability of frequency converter under the abominable operational environment of many vibrations.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the structural representation of metal fixation clip among Fig. 1.
Embodiment
Below with reference to accompanying drawing the utility model is described in further detail.
Visible by Fig. 1, Fig. 2: the utility model comprises: at least one group of electric capacity; Every group is 6 electric capacity 4; The top of every group electric capacity 4 is fixing with metal fixation clip 1 through a rubber blanket 2.
The utility model is fixed on metal fixation clip 1 through double-screw bolt among Fig. 25 and the through hole 3 among Fig. 1 the top of electric capacity 4.Through metal platen the top of electric capacity is fixed, made electric capacity can not shake because of vibration and be shifted; Between metal platen and electric capacity, also increased one deck rubber blanket 2, rubber blanket of the common use of per 6 electric capacity.Rubber blanket is fixed between metal platen and the electric capacity firmly, plays fixed capacity, prevents the effect of vibrating.The metal fixation clip is in the installation and the use of capacitive head, prevents that electric capacity from rocking because of the influence of being vibrated produces and be shifted, and makes the loosening probability of electric capacity wiring pin generation solder joint be reduced; Between metal fixation clip and electric capacity, increase rubber blanket, make in installation process, electric capacity can not be affected the protection that makes the installation of electric capacity and fixedly obtain cushioning because different double-screw bolts produce different pressure when mounted.
The utility model is compared with common frequency converter owing to adopt above-mentioned scheme, has stronger freedom from vibration, has guaranteed the reliability of frequency converter under the abominable operational environment of many vibrations.And structure and uncomplicated, practicality and good reliability are installed simply.
Claims (1)
1. one kind is applicable to the frequency converter under many vibration operational environments, comprising: at least one group of electric capacity; Every group is 6 electric capacity; It is characterized in that: the top of every group electric capacity is fixed through a rubber blanket and metal fixation clip.
