Description
Technical field
The invention belongs to erasing discharge equipment technical field, particularly a kind of energy automatic safe discharges the apparatus and method of remaining capacity in Deperming Facility.
Background technology
The demagnetization principle of magnetic-based storage media Deperming Facility or title degausser is, is discharged, discharge coil produces powerful exciting current with the capacitor being full of electric charge by discharge coil, and then produces highfield.Because in Deperming Facility work, the voltage compare of capacitor is high, and capacitor is energy-storage travelling wave tube, and after electric discharge or due to certain fault or abnormal the electric charge on capacitor can be caused to bleed off completely, there is electric leakage hidden danger, this can cause Danger Electric shock risk to user of service.
Summary of the invention
The object of the present invention is to provide a kind of automatic safe electric discharge device and safe-discharge method, can automatically the electric charge on storage capacitor be forced to bleed off after Deperming Facility power-off, avoid causing danger of hazardous electrical discharges.
A kind of Deperming Facility automatic safe electric discharge device, is characterized in that comprising controller, comparator, device power supply (DPS) voltage sampling circuit, reference voltage generating circuit, uninterrupted power supply, switch and discharge loop; Described discharge loop, switch are connected with Deperming Facility storage capacitor; Described controller is connected with comparator, switch, and controller is from comparator Received signal strength, and the connected sum according to Signal-controlled switch disconnects; Comparator is connected with device power supply (DPS) voltage sampling circuit and reference voltage generating circuit; Device power supply (DPS) voltage sampling circuit is connected with Deperming Facility power supply, can generate and export the sampled voltage of Deperming Facility power supply; Reference voltage generating circuit is connected with uninterrupted power supply, can generate and output reference voltage; Described automatic safe electric discharge device is powered by uninterrupted power supply, and the effect of uninterrupted power supply is to ensure that automatic safe electric discharge device can independent operation, by the impact of Deperming Facility whether power-off itself.
Described discharge loop can be the discharge coil of resistance, semiconductor device or Deperming Facility inside.
Described switch can be semiconductor device or relay or triode or controllable silicon.
The safe-discharge method of this Deperming Facility is used to comprise the steps:
The first step: starting uninterrupted power supply is that device is powered
Second step: reference voltage generating circuit generates reference voltage and is transferred to comparator, device power supply (DPS) voltage sampling circuit generates the sampled voltage of device power supply (DPS) and is transferred to comparator simultaneously;
3rd step: the sampled voltage of comparator compare facilities power supply and reference voltage;
4th step: if the sampled voltage of device power supply (DPS) is less than or equal to reference voltage, comparator is to controller signal transmission, and controller controls turn on-switch, and capacitor is communicated with discharge loop and discharges;
5th step: if the sampled voltage of device power supply (DPS) is greater than reference voltage, comparator is to controller signal transmission, and controller controls cut-off switch, and capacitor is not communicated with discharge loop.
The output voltage of described uninterrupted power supply should be not more than 36 volts, and reference voltage should be not more than 36 volts, can ensure that safe discharge device itself can not cause Danger Electric shock risk while realizing safe-discharge.
After Deperming Facility power-off, sampled voltage and the reference voltage of device power supply (DPS) is generated under uninterrupted power supply powered operation, comparator compares two voltages, when the sampled voltage of device power supply (DPS) being detected lower than reference voltage, at this moment illustrate that Deperming Facility power supply is closed, and no longer carries out degaussing operation, comparator feeds back signal to controller, controller control switch is communicated with, and Deperming Facility storage capacitor and discharge loop is connected, thus by the residual charge release in capacitor.If Deperming Facility power supply is in "on" position, the sampled voltage of device power supply (DPS) is inevitable higher than reference voltage, controller is cut-off switch then, do not discharge, at this moment Deperming Facility can carry out normal demagnetization action, can not mutually disturb between the degaussing gear of Deperming Facility and automatic safe electric discharge device, all processes can carry out, automatically without the need to manual intervention.
Structure of the present invention is simple, realizes automatic discharging, avoids artificial mechanism to operate problems, the problem includes: electric leakage, discharge and can not wait problem, practical, safe and reliable.
