Abstract
The utility model discloses the chain gating device of a kind of high voltage source output safety, comprise be linked in sequence power supply, high voltage source output counter door interlock switch, isolation optocoupler, reverser, level transferring chip and high voltage source controller; Isolation optocoupler exports 5V signal; The output of isolation optocoupler after inverter, then is connected to level transferring chip, is converted to the signal that high voltage source controller can bear, is finally connected to high voltage source controller.When adopting this device to only have High voltage output cabinet door to be closed, high voltage source could start, if open High voltage output cabinet door when high voltage source is run, then high voltage source can quit work, and substantially increases security performance.
Description
Technical field
The utility model relates to a kind of safety interlock, specifically the chain gating device of a kind of high voltage source output safety.
Background technology
Present stage, along with the fast development of national economy, the demand of high voltage source is increasing, its functional requirement is also more and more higher, and require that high voltage source technology is more advanced, function is more perfect, structure is more reasonable, could meet the requirement that market constantly changes, win the trust of user.Also unsatisfactory in domestic common high voltage source security protection problem, it shows as: domestic common high voltage source output counter door only joins padlock or electromagnetic lock mostly, Field Force can not get the fail safe prompting of definition, and high voltage source output counter padlock or electromagnetic lock are when there being key, be easy to open high voltage source output counter, once open cabinet door, Field Force will be subject to the danger that high pressure gets an electric shock, and causes huge loss to the life of people and property.
Summary of the invention
The purpose of this utility model is to provide the chain gating device of a kind of high voltage source output safety, when adopting this device to only have High voltage output cabinet door to be closed, high voltage source could start, if open High voltage output cabinet door when high voltage source is run, then high voltage source can quit work, and substantially increases security performance.
The purpose of this utility model is achieved through the following technical solutions:
The chain gating device of a kind of high voltage source output safety, is characterized in that: this device comprise be linked in sequence power supply, the interlock switch of high voltage source output counter door, isolation optocoupler, reverser, level transferring chip and high voltage source controller; Isolation optocoupler exports 5V signal; The output of isolation optocoupler after inverter, then is connected to level transferring chip, is converted to the signal that high voltage source controller can bear, is finally connected to high voltage source controller.
In the utility model, be connected with the interlock switch of high voltage source output counter door after described power supply comprises a 24V voltage source and resistance R, 24V voltage source and resistance R connects.Power supply is connected to isolation optocoupler after the interlock switch of high voltage source output counter door, and isolation optocoupler exports 5V signal.
When high voltage source output counter door is opened, the interlock switch of high voltage source output counter door disconnects, and high voltage source controller cuts out high voltage source, and namely high voltage source can not start or operating high voltage source quits work.
When adopting this device to only have High voltage output cabinet door to be closed, high voltage source could start, if open High voltage output cabinet door when high voltage source is run, then high voltage source can quit work, and substantially increases security performance.
Accompanying drawing explanation
Fig. 1 is systematic schematic diagram of the present utility model.
Embodiment
The chain gating device of a kind of high voltage source output safety, is shown in Fig. 1, this device comprise be linked in sequence power supply 1, the interlock switch 2 of high voltage source output counter door, isolation optocoupler 3, reverser 4, level transferring chip 5 and high voltage source controller 6; Isolation optocoupler exports 5V signal; The output of isolation optocoupler after inverter, then is connected to level transferring chip, is converted to the signal that high voltage source controller can bear, is finally connected to high voltage source controller.
Be connected with the interlock switch of high voltage source output counter door after power supply comprises a 24V voltage source and resistance R, 24V voltage source and resistance R connects.Be connected to isolation optocoupler, isolation optocoupler exports 5V signal.
When high voltage source output counter door is opened, when namely the interlock switch of described high voltage source output counter door disconnects, high voltage source can not start or operating high voltage source quits work.When only having High voltage output cabinet door to be closed, high voltage source could start, if open High voltage output cabinet door when high voltage source is run, then high voltage source can quit work, and substantially increases security performance.
