Description

Technical Field

The utility model relates to a ATS (Automatic transfer switching equipment) field especially relates to an Automatic transfer switch simulator and input/output circuit thereof.

Background

ATS (Automatic transfer switching) is used as a core device for improving power supply reliability, and is increasingly applied to various industrial, medical and data center places. The ATS has the main function that when the power supply of a main circuit of a power supply system is in a problem, the ATS needs to switch a load to a standby power supply circuit in time so as to ensure the uninterrupted operation of the load.

The ATS mainly comprises two parts, namely an ATS switch and an ATS controller. The ATS switch controller is operably connected to the ATS switch and is capable of controlling the ATS switch to switch between different switch states. The ATS switch is electromechanical equipment and is load-bearing equipment of a primary circuit, and the ATS switch is used for moving the switch to different positions according to instructions of the ATS controller to realize switching of the switch. The ATS controller is an electronic device, is the brain of the ATS and is responsible for monitoring the power quality in real time and running a switching logic, and drives an ATS switch to perform corresponding switching actions according to different power states.

Currently, ATS switches can be roughly classified into an electromagnetic coil type and a motor pre-stored energy type according to types and operating speeds, and can be classified into various current types according to the magnitude of rated current. In general, the types of ATS switches are not more than ten.

It can be understood that the ATS controller, as an electronic control device, generally needs to be adaptable to different types of ATS switches, but because the types of the ATS switches are numerous, different types of ATS switches have a series of differences, such as different action times, different driving manners, different working positions, different logic states of various feedback signals, different intermediate position dwell times, and the like, in an actual application process, the ATS controller needs to be adaptable to different ATS switches, and different simulation experiments and debugging work needs to be performed on different ATS switches.

Particularly, for research and development and testing of the ATS controller, in order to enable the ATS controller to achieve stable and reliable work for different kinds of ATS switches, the ATS controller must carry various kinds of ATS switches in a whole series to perform adaptation testing, and the ATS switch with a large current usually has a heavy weight and a large volume, is inconvenient to carry, brings a series of difficulties and problems to the building of a testing environment, the protection of a testing site, the protection of personnel in the testing process, the adjustment of wiring and the like, is inconvenient to debug, consumes a large amount of time in the testing process, and increases the research and development period of the ATS controller.

It should be noted that, in order to obtain the adaptive performance of the ATS controller for a type of ATS switch, testing and debugging operations for a plurality of ATS switches of a type of ATS switch are usually required, which undoubtedly further increases the difficulty of the testing and debugging processes for the ATS switches.

In summary, how to solve a series of problems of difficulty in moving an ATS switch, difficulty in building a debugging environment, and tedious debugging operation process, which are faced in the debugging process of the conventional ATS controller, becomes a problem that further development of the ATS is restricted and needs to be solved urgently.
