Protection of radio equipment against increase of tension of a network
the Most part of modern radio equipment has pulse power supplies which in case of an overload fail. Constantly to supervise mains voltage it is inconvenient and it is not effective. The overload at working equipment can occur at any time. The offered device allows to prevent damage of electrodevices and radio engineering from tension increase. The simplest option of protection of equipment from an overload can be executed, using the special gazorazryadnik included after entrance safety locks. It has such characteristic that gas breakdown in the case occurs at excess of operating tension above 270 Century. The worked rated sportsman forces to burn down entrance safety locks that will interrupt tension giving on all switched-on devices.
the Main shortcomings of a gazorazryadnik is its deficiency and a noncontrollable threshold of operation.
- Automatic protection of network radio equipment
- A food of low-voltage radio equipment from a network
- The simplest circuits of power supplies for various equipment
- Automatic disconnection of the amplifier from a network
- Two devices for emergency protection against excess of mains voltage
