Abstract
The invention discloses a kind of cabinet door safety device of variable-frequency power sources cabinet, in cabinet door both sides installation infrared opposite-radiation switch, the reception head output end connection auxiliary reclay of infrared opposite-radiation switch, auxiliary reclay connection control variable-frequency power sources cabinet power supply.Variable-frequency power sources cabinet is operationally; if someone opens variable-frequency power sources cabinet cabinet door; now cabinet door blocks the infrared ray of infrared opposite-radiation switch transmitting terminal; infrared receiver end will send level signal; act DC24 auxiliary reclays; variable-frequency power sources is shut down using the contact of auxiliary reclay, avoids dangerous generation.The present invention is switched with infrared opposite-radiation, auxiliary reclay realizes that when cabinet door is opened the shutdown to variable-frequency power sources cabinet is simple in construction, easy to control, and cabinet operating personnel provide a safety guarantee for variable-frequency power sources.
Description
Technical field
The present invention relates to a kind of variable-frequency power sources cabinet, more particularly to a kind of cabinet door safety device of variable-frequency power sources cabinet.
Background technology
Existing variable-frequency power sources cabinet in the process of running because layman also can arbitrarily open variable-frequency power sources cabinet cabinet
Door, this just brings potential safety hazard to production, for example electric shock is hurted sb.'s feelings, and the appliance component that longtime running has is it some times happens that blast
Etc. accident, although these accidents are accidental small probability events, the variable-frequency power sources cabinet of domestic manufacturer's production does not all design cabinet door
Safety device.
The content of the invention
For above-mentioned technical problem underlying, it is an object of the invention to provide a kind of cabinet door of variable-frequency power sources cabinet peace
Full device, for variable-frequency power sources, cabinet operating personnel provide a safety guarantee.
To achieve the above object, the technological means taken of the present invention is：A kind of cabinet door safety device of variable-frequency power sources cabinet,
It is middle in cabinet door both sides installation infrared opposite-radiation switch, the reception head output end connection auxiliary reclay of infrared opposite-radiation switch
Relay connection control variable-frequency power sources cabinet power supply.
Further, 0~10m of range region of the infrared opposite-radiation switch, 10~30V of operating voltage, operating current<
100mA。
Further, the auxiliary reclay is DC24V auxiliary reclays.
Further, the infrared opposite-radiation switch is arranged on the upper lateral part of cabinet door two, and front/rear door is respectively set a pair, and two red
The output end that outside line receives head to penetrating switch is touched by the coil of resistance connection auxiliary reclay, the normally closed of auxiliary reclay respectively
Point is arranged in the power circuit of variable-frequency power sources cabinet.
Operation principle of the present invention：Variable-frequency power sources cabinet operationally, if someone opens variable-frequency power sources cabinet cabinet door, now cabinet door
The infrared ray of infrared opposite-radiation switch transmitting terminal is blocked, infrared receiver end will send level signal, make relay among DC24
Device acts, and shuts down variable-frequency power sources using the contact of auxiliary reclay, avoids dangerous generation.
The beneficial effects of the present invention are：Switched with infrared opposite-radiation, auxiliary reclay realize when cabinet door is opened, to change
The shutdown of frequency power cabinet, simple in construction, easy to control, for variable-frequency power sources, cabinet operating personnel provide a safety guarantee.
Brief description of the drawings
The present invention is further elaborated with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is schematic block circuit diagram of the present invention.
Embodiment
As shown in figure 1, a kind of cabinet door safety device of variable-frequency power sources cabinet, in cabinet door both sides, installation infrared opposite-radiation switchs,
The reception head output end connection auxiliary reclay of infrared opposite-radiation switch, auxiliary reclay connection control variable-frequency power sources cabinet power supply.
0~10m of range region of the infrared opposite-radiation switch, 10~30V of operating voltage, operating current<100mA.It is existing
Using German Xi Ke companies infrared opposite-radiation switch, this switch way of output has two kinds of forms of L and D, is user-friendly.
The auxiliary reclay is DC24V auxiliary reclays.
The infrared opposite-radiation switch is arranged on the upper lateral part of cabinet door two, and front/rear door is respectively set a pair, two infrared opposite-radiations
The output end that switch receives head is arranged on by the coil of resistance connection auxiliary reclay, the normally-closed contact of auxiliary reclay respectively
In the shutdown circuit of variable-frequency power sources cabinet.
Infrared opposite-radiation switch is arranged on the upper lateral part of cabinet door two, can be prevented because being arranged on bottom, may be by other
Object blocks caused malfunction.
Operationally, if someone opens variable-frequency power sources cabinet cabinet door, now cabinet door blocks infrared opposite-radiation to variable-frequency power sources cabinet
The infrared ray of transmitting terminal is switched, infrared receiver end will send level signal, act DC24 auxiliary reclays, utilize centre
The contact of relay shuts down variable-frequency power sources, avoids dangerous generation.
The present invention is switched with infrared opposite-radiation, auxiliary reclay is realized when cabinet door is opened, the shutdown to variable-frequency power sources cabinet,
Simple in construction, easy to control, for variable-frequency power sources, cabinet operating personnel provide a safety guarantee.
One of ordinary skill in the art will appreciate that：Various embodiments above is merely illustrative of the technical solution of the present invention, and
It is non-that it is limited；Although the present invention is described in detail with reference to foregoing embodiments, one of ordinary skill in the art
It should be understood that：It can still modify to the technical scheme described in foregoing embodiments, either to which part or
All technical characteristic carries out equivalent substitution；And these modifications or replacement, the essence of appropriate technical solution is departed from this hair
The scope of bright each embodiment technical scheme.
