Description

Technical Field

[0001] The utility model relates to a chassis vehicle with double position confirmation, belonging to the field of chassis vehicles. Background Art

[0002] A switch cabinet is an electrical device. The external line of the switch cabinet first enters the main control switch inside the cabinet, and then enters the sub-control switch. Each branch is set according to its needs. Such as instruments, automatic control, motor magnetic switches, various AC contactors, etc. Some also have high-voltage and low-voltage room switch cabinets, with high-voltage busbars, such as power plants, etc. Some also have low-frequency load shedding to protect the main equipment.

[0003] Switch cabinets are usually used in places such as substations. In existing switch cabinets, in order to enable the circuit breaker to easily realize the push-in (pushing from the test position to the working position) and exit (exiting the test position from the working position), a chassis vehicle is generally used to carry circuit breakers and other electrical appliances, and the running wheels installed on the chassis vehicle move forward or backward on the track in the switch cabinet. However, due to the single method for determining the status and position of primary and secondary equipment, the position is only confirmed at the indicator after the screw rod is in place, which poses a great safety hazard and cannot meet the "double confirmation" determination requirements of equipment position according to regulations.

The test position indicator 31 and the working position indicator 32 are used to output signals to the indication system to indicate the position of the circuit breaker when the circuit breaker is in the test position or the working position.

[0036] The test position indicator 31 is a test position micro switch or a test position proximity switch or a test position sensor; the working position indicator 32 is a working position micro switch or a working position proximity switch or a working position sensor.
