General introduce:
the Mechanical life of the circuit breaker refers to the resistance to mechanical Wear of the circuit breaker and can be characterized by the number of times the No-load operation cycle (ie, the main contact is not current), which is Achieved before the circuit breaker needs to be repaired or replaced with any Mechanical parts Mechanical life times. Each operation cycle includes a closing Operation followed by a disconnection operation. Circuit breaker running-in Period refers to the circuit breaker mechanical parts in the initial operation of contact, friction, bite the process, in order to achieve the best between the various components with. the operation cycle includes, in addition to the Closing operation and the accompanying disconnection operation, the reclosing Operation (in minutes -0.3s-score) in some cases.

the System has been researched and designed for the mechanical life or mechanical Running of the high and low voltage circuit breakers (hereinafter referred to As the running test system) to meet the basic requirements of safety, Reliability and improvement of test efficiency and real-time monitoring. the Test system can perform and meet the national standard GB 1984-2014 mechanical Life test project requirements.

the System can control multiple circuit breakers at the same time, run-in test System is divided into 3 stations / 4 stations / 6 stations / 8 stations of the Test equipment, you can simultaneously control 3/4/6 / 8 sets of circuit Breakers for running test. the test system to industrial control computer as the core, the computer software system as a platform for parameter setting, Circuit breaker control and analysis of results, save. and the software system Has a perfect user rights management and data management functions, you can Record the process of running parameters of the changes in the state, the Formation of the corresponding test process file, easy to run after the end of the circuit breaker stability to make a correct assessment and analysis.
Main Features:

(1)  Clear and accurate graphical interface:
Windows operating system, familiar with the man-machine interface. Equipment for the entire test process for each step of the results and the final results Are recorded with accurate text or graphic markings, so that the operator to Keep abreast of the test situation.

(2) to assess the test data biased the statistical means:
Equipment in the Experimental process, according to the product of multiple test results, according to the actual design of statistical parameters and algorithms, given the run-in Statistical results. for example, it is possible to evaluate whether there is a Jam or unstable phenomenon during the running of the switch.

(3)Data Communicate through the network:
with the development of the network, the use of network technology exchange is already very common. the device software System designed a reasonable data structure, the application of a common file Format, so that any third-party system in the test results after the file can Be very smooth interpretation.

(4) with fault security measures and sound and light alarm function:
without the Need for laboratory personnel to accompany the whole monitoring: run-in process Generally at least dozens to hundreds of times, or even more long work process, the experimental staff without the need to accompany the whole monitoring, In the event of failure equipment will automatically cut off the power, and sound and light alarm, suggesting that the need to lift the fault.

(5) Equipment design process to consider the issue of grid pollution:
Regardless of A few stations running the same equipment, the same time only one switch Action, to avoid more than one action on the grid caused by pollution.

(7) Easy to operate:
Only to set the parameters needed, it will complete the run-in Function automatically. and a perfect user rights management and data Management functions, the process of running parameters of the changes tracked In the situation, the formation of the corresponding document, easy to run after the end of the circuit breaker stability to make a correct assessment.

Power Supply Parameters:

Due to the fact that each station is relatively independent in design, the Technical parameters of each station are the same. Here is a station as an Example.

Rated Input voltage: three-phase four-wire AC380V ± 10%, 50Hz

Each Station has an independent power supply module
