Description

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.

Features

(1). 8.4"LED panel, windows operation system, humanized operation interface, visualized interface, touch screen, all these are handy for use.
(2). High-speed thermal printer is used for printing test data on site.
(3). Interior integrated operational power supply , without needing on-site secondary power supply, is convenient and easy to use on site. It provides the range  adjustable power supply from DC10~260V with 20A of current. Randomly set the operation voltage values of breaking and closing coil, and conduct an low voltage operation test of breaker.
(4). Equip with liner sensors, rotation sensors, universal sensors and holders, and dedicated fixed multifunction connections, which could be easy to mount.
(5). It is fit for all types about SF switch, GIS composite apparatus, vacuum switch,  oil switch, produced in domestic or abroad.
(6). Obtain overall data and graphs by one on-off action.
(7). Mainframe can store 6,000 groups of on-site test data (support external memory card),internal real time clock, easy to file.
(8). Equip with USB interface, which could save data directly in USB disk, and upload in computer to analyze and preserve.
(9). Simultaneously measure 12 circuits metal contact fractures.
(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.
