Overview

1 The scope of product

TY260 microcomputer integrated protection measurement and control device is suitable for industrial and civil 20KV and the following voltage levels of lines and plant protection and measurement and control, users can switch on their own line or plant protection procedures.

Products are mainly for ring network cabinet design can also be used for ordinary switch cabinet, small size, shallow depth, with complete current protection, voltage protection, switch input (programmable setting export, tripping or alarm), relay output, and communication function.

3.Main function

TY260 protection device mainly in distribution system operation equipment protection, telemetry, remote control, provide perfect protection and control functions, the consideration of different regions, different user needs and maximize do debugging is simple, easy to use, small amount of maintenance etc.. According to the application consists of line protection, transformer protection .

Protection function: protection device in accordance with the distribution protection device requirements with complete protection function, generally does not have protection function of power transmission system is unique, as phase reclosing, the direction of protection;

Control functions: to provide system level measurement parameters measurement, measurement accuracy is better than the same level of measuring instruments, but not used as a measurement; the system device is mainly the two table method, in addition to providing basic measurement parameters such as current, voltage, etc. also provides active power, reactive power, power factor and other parameters are measured, in the setting of modified CT and Pt ratio can also display a value can be replaced by digital measuring instrument;

Communication: TY260 device provides standard RS485 communication interface and Modbus communication protocol to facilitate networking and information transmission;

Telemetry and telemetry: send the switch and protection plate state and set the value of code and accident alarm class telesignalling. While the configuration of the switch remote control switching, protection function of the soft pressing plate of the cast back, and protection fixed value changes, switching value.

Human-computerinterface: TY260 device using liquid crystal display and simplified operation button as a means of man-machine dialogue, the Chinese version of the menu content.
