The invention belongs to the technical field of power distribution room
safety monitoring, and specifically discloses a real-time poison
gas monitoring system for a high-
voltage switch cabinet of a power distribution room. The real-time poison
gas monitoring system comprises a cabinet body, wherein vent holes are uniformly formed in outer walls of left and right sides of the cabinet body; an alarmlamp is mounted on the top of the cabinet body; and an
oxygen gas tank is arranged on the bottom of the inner cavity of the cabinet body. In order to avoid the problem that
carbon monoxide poisoningis caused as a technologist does not timely observe and monitor the
system, and field emergent treatment cannot be performed under a follow-up emergency situation, a
gas exchange control valve is adopted to seal the high-
voltage switch cabinet, so that spread of
carbon monoxide is reduced; a great deal of
oxygen gas is pumped out to reduce content of
carbon monoxide outside, so that poisoning andworsening are avoided; and a sound outlet hole is designed, so that remind of the technologist is improved while concentration of carbon
monoxide is increased, and timely reminding before poisoning orat the initial stage of poisoning is convenient, and therefore, corresponding remediation measures are taken, safety protection effect is improved, and protection on the power distribution room is improved.
