Abstract: An agricultural work vehicle having an air supply device includes: an air compressor for pressurizing air; an air tank for storing the air compressed by means of the air compressor; a pressure sensor for measuring the pressure of the air stored in the air tank or atmospheric pressure; a controller for stopping the operation of the air compressor when the measured pressure exceeds a first reference value; and an air pressure regulator for discharging, to the outside, the air inside an air pressure circuit system so as to reduce the pressure when the pressure of the air stored in the air tank exceeds a second reference value.

Abstract: The present disclosure discloses a switchgear including a housing, a door, a circuit breaker main body, a transfer part, and an interlock device. Here, a front side of the housing is opened to form an external appearance thereof. In addition, the door is hinge-coupled to the front side of the housing to open and close the front side of the housing. The circuit breaker main body is disposed inside the housing to be movable forward and rearward. The transfer part is disposed between the housing and the circuit breaker main body to move the circuit breaker main body. The interlock device restricts the driving of the transfer part when the door is opened.
