CB timing tester / CB timing test Set Introduction

With the development of society, the electricity security is required to be more by people, ZC-300D burdens the dual-control and protection in electric system, whose performance relates to the operation of electric system . mechanic parameter is one of indispensable parameter in analyzing the performance of breaker. The comprehensive characteristic tester of high-voltage switch , namely, the mechanic characteristic tester, is according to the latest version of < high-voltage AC circuit breaker> GB1984-2003 as design model, referring to the third part of PRC’s power industry standards <Genera technical specifications for high voltage test equipment>, and designing based on DL/T846.3-2004, which inspect various grades of voltages in high-voltage circuit breaker’s mechanic dynamic characteristic parameters about oil lack, oil excess, vacuum and sulfur hexafluoride, to provide convenience to many kinds of breakers.

CB timing tester / CB timing test Set Characteristics

[01] 8.4”LED panel, windows operation system, humanized operation interface, visualized interface, touch screen, all these are handy for use.

It provides the range adjustable power supply from DC20~265V with 20A of current. Randomly set the operation voltage values of breaking and closing coil, and conduct an low voltage operation test of breaker.

[04] Equip with liner sensors, rotation sensors, universal sensors and holders, and dedicated fixed multifunction connections, which could be easy to mount.

[05] It is fit for all types about SF switch, GIS composite apparatus, vacuum switch, oil switch, produced in domestic or abroad.

[06] Obtain overall data and graphs by one on-off action.

[07] Mainframe can store 6,000 groups of on-site test data (support external memory card),internal real time clock, easy to file.

[08] Equip with USB interface, which could save data directly in USB disk, and upload in computer to analyze and preserve.

[09] Simultaneously measure 12 circuits metal contact fractures, 6 circuits closing resisters.

[10] Generate standard envelop curves through the test data of switch testing from several instruments (2~10), then conduct analyses and comparisons, and switch vibration frequency analyses as well.

[11] Internal anti-jamming circuit could meet 500KV inner reliable use in transformer substation.
