| Purpose & brief description |
| ● It is mainly applicable to mechanical characteristic parameter test and characteristic analysis of switches with more oil, less oil, SF6, vacuum, load switch, etc. It can carry out fracture time, speed, synchronization, stroke, bounce, operating current, low voltage action, combined operation test, etc. of various switches. ● Application: power product manufacturing companies, power operation departments, scientific research institutions and colleges and universities. ● Application products: circuit breaker, vacuum switch of all metal contacts, SF6 switch, GIS switch, load switch, etc. |
| Test purpose |
| ● The opening and closing speed, time and degree of different periods of the circuit breaker, as well as the action voltage of the opening and closing coil, directly affect the closing and breaking performance of the circuit breaker, and have a great impact on relay protection, automatic reclosing and the stability of the power grid. ● For oil circuit breaker, the decrease of rigid minute speed will increase the arcing time, especially in case of short-circuit fault, the contact may be burned, fuel injection or even explosion. The decrease of rigid closing speed, when closing in short-circuit fault, will cause contact vibration or make it in a stagnant state due to the effect of blocking the electric power of outlet closing, which is also easy to cause explosion, especially in the case of unsuccessful automatic reclosing. On the contrary, if the speed is too high, the moving mechanism will receive excessive mechanical stress, resulting in damage to individual parts or shortening the service life, which is not allowed. ● The opening and closing of the circuit breaker in different periods will cut off the non full phase access of the line or transformer, resulting in overvoltage endangering the insulation. |

| Technical features |
| ● High reliability integrated operation power supply: it has the function of preventing port short circuit, effectively overcoming the problem of power failure of this kind of tester, and has higher safety performance. ● Intelligent human-computer interaction interface: any person can fully master the use method of the instrument within 5-10 minutes ● powerful curve analysis interface: opening and closing time, bounce, synchronization, stroke, speed, voltage, current and other test data can be calculated automatically, and can also be customized from the curve ● Speed test and are convenient: two imported sensors, corner and straight line, are equipped as standard, with firm quality and high accuracy; The user-defined speed calculation function interface can meet the speed definition requirements of any switch. ● Automatic low voltage test: in addition to ordinary opening and closing operations, manual or automatic low voltage test can also be carried out on the switch. The automatic low voltage test can automatically calculate the minimum starting voltage, rated voltage ratio, etc. with only one setting. Combined operation tests such as opening and closing, closing and opening, opening and closing can also be carried out. ● Bluetooth wireless upload function is optional to support tablet PC. |
