Abstract
The utility model discloses a salt fog box protection device. A water level indicator is arranged on a saturation device, a magnetic floater is arranged in the water level indicator, a magnetic switch is arranged on a corresponding outer side wall, and the magnetic switch is connected to a control circuit. The control circuit comprises three paths of parallel circuits which are connected to both ends of a power supply in parallel, wherein the first path of the parallel circuits comprises the magnetic switch and a relay coil which are connected in series; the second path of the parallel circuits comprises an AC contactor coil, a normally open contact of a temperature controller, and a normally closed contact of a relay which are connected in series; and the third path of the parallel circuits comprises a normally open contact of the relay and a warning light which are connected in series. The salt fog box protection device is simple in structure and practical in function. An operator can see the water level more easily. The protection device disclosed by the utility model can cut off the power automatically when little pure water left and alarm, thereby preventing a salt fog test box device from being damaged.
Description
Technical field
The utility model relates to a kind of salt fog cabinet protective device, is battery steel shell a kind of protective device to equipment when doing artificial seawater salt mist test.
Background technology
At present, full to close device be the container that stainless steel material is done, and the material that the inside is used is that pure water and the pure full device the inside of closing of compressed air (being continuous or interrupted air inlet during work) have pressure, pure water conductivity very low (resistance is very large) transparent again; During operation the light current utmost point be not easy to detect near and can not automatically control, forceful electric power is deposited great potential safety hazard; Water works on when few, thereby makes device damage.
The utility model content
The utility model provides a kind of salt fog cabinet protective device, and battery steel shell can effectively be protected equipment when doing salt mist test, be unlikely to damage equipment.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of salt fog cabinet protective device, and full close device and be provided with water-level gauge, it is floating to be provided with magnetic water in the water-level gauge, and corresponding lateral wall is provided with magnetic switch, and magnetic switch is connected into control circuit.
Control circuit comprises three road parallel circuitss that are connected in parallel on both ends of power, first via parallel circuits comprises magnetic switch and the relay coil of series connection, the the second road parallel circuits comprises ac contactor coil, temperature controller normally opened contact and the relay normally-closed contact of series connection, and the Third Road parallel circuits comprises relay normally open contact and the warning lamp of series connection.
Simple in structure, the practical function of the utility model, the visual water level of operator is easier, can also report to the police by auto-breaking when pure water is few, prevents the salt spray test chamber device damage.
