Background technology
The demagnetization principle of magnetic-based storage media Deperming Facility or title degausser is, with the capacitor that is full of electric charge, by discharge coil, discharges, and produces powerful exciting current on discharge coil, and then produces highfield.Because the voltage ratio of capacitor in Deperming Facility work is higher, and capacitor is energy-storage travelling wave tube, after electric discharge or due to certain fault or extremely can cause the electric charge on capacitor to bleed off completely, has electric leakage hidden danger, and 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, can after Deperming Facility power-off, automatically the electric charge on accumulate capacitor be forced to bleed off, avoid causing electric leakage dangerous.
A 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 and Deperming Facility accumulate capacitor's series; Described controller is connected with comparator, switch, and controller receives signal from comparator, according to the connected sum of Signal-controlled switch, disconnects; Comparator is connected with reference voltage generating circuit with device power supply (DPS) voltage sampling 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 guarantee that automatic safe electric discharge device can independent operation, is not subject to the whether impact of power-off of Deperming Facility itself.
Described Deperming Facility automatic discharge device, after Deperming Facility power-off, by uninterrupted power supply, powered, generate sampled voltage and the reference voltage of device power supply (DPS), comparator compares two voltages, if the sampled voltage of device power supply (DPS) is less than or equal to reference voltage, comparator is to controller signal transmission, controller is controlled turn on-switch, and capacitor is communicated with electric discharge with discharge loop; If the sampled voltage of device power supply (DPS) is greater than reference voltage, comparator is to controller signal transmission, and controller is controlled cut-off switch, and capacitor is not communicated with discharge loop.The sampled voltage that device power supply (DPS) detected when controller is during lower than reference voltage, this explanation Deperming Facility power supply is closed, no longer carry out demagnetization work, comparator feeds back signal to controller, controller control switch is communicated with, Deperming Facility accumulate capacitor and discharge loop are connected, thereby the residual charge in capacitor is discharged.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, do not discharge, at this moment Deperming Facility can carry out normal demagnetization action, can phase mutual interference between the degaussing gear of Deperming Facility and automatic safe electric discharge device, all processes can carry out automatically, without manual intervention.
Described discharge loop can be the discharge coil of resistance, semiconductor device or Deperming Facility inside.
