A device for detecting electromagnetic radiation class electrical equipment's explosion-proof can

The utility model discloses a device for detecting electromagnetic radiation class electrical equipment's explosion-proof can, the device include shielded cell, calibrater, receiving antenna, wave guide, output matching network, spark test apparatus and oscillograph, said calibrater, receiving antenna, wave guide and output matching network all are provided in the shielded cell, one end that calibrater and DUT are provided the shielded cell, and output matching network is provided the other end of shielded cell, after receiving antenna receives the electromagnetic radiation that the DUT sent, inputs output matching network through the wave guide, and spark test apparatus establishes ties in output matching network's return circuit and is provided outside the shielded cell, and the oscillograph connects in parallel at spark test apparatus's both ends. The utility model discloses this device realization means is simple, and accessible time, detect electromagnetic radiation class electrical equipment effectively, and the security is high, but the wide application is in electromagnetic radiation class electrical equipment's explosion-proof can detection area.
