Remote PC Computer Control System

1: remote control system: the upper computer software is installed in the standard Windows system, the operation is simple and easy to learn, to meet the test requirements. Real-time recording of current; voltage; temperature, time, observation and analysis simple and convenient.The control distance ≥10 m.

Structure Description

1: short circuit mainframe

Double safety pneumatic copper contactor short circuit mode :1 normally open contactor, the other 1 is normally closed contactor. The double-axis high-precision cylinder with short-circuit opening contactor will close the copper connecting block of positive and negative electrode to form a circuit to achieve short-circuit purpose. When the short-circuit time is reached, the contactor will open normally, and the contactor will also open normally. The purpose is to prevent the normally open contactor from accidentally sintering, and the normally closed contactor can open in time, so as to avoid the safety accident caused by the battery short-circuit test because the contactor can not break.

Vacuum arc extinguishing mode: the double safety contactor is installed in the vacuum box, the vacuum pumping makes the air in the box thin, the contact surface of the contactor will not produce arc when short circuit, so that the contact surface will not be sintered, and the service life will be prolonged to reduce the failure rate.

Vacuum control system: through vacuum pump, vacuum valve, pressure sensor, high pressure gas pipe, joint and other vacuum connectors to the box internal pressure control.

Security protection function

(1) Emergency stop protection function:

The equipment and the computer control cabinet are each equipped with an emergency stop switch.When an emergency occurs or you want to stop the test, you can press this switch to stop the output of the control board and stop all test actions.

(2)Three-color lights sound and light alarm system:

The equipment is equipped with a three-color alarm lamp, the light flashing alarm reminds the personnel equipment different test status.

(3) Fault display

(4) Power-off protection function

(5) Electrical safety protection;

(6) Leakage protection, overheating protection;

Equipment installation conditions:

1. installation in place: the equipment can be unloaded through a 2 ton forklift, after moving into the laboratory, adjust the distance between the rear part of the equipment and the left and right sides of the wall ≥1000 mm, the front operation space ≥1500 to facilitate the operation test, after fixing the equipment. Power cord and compressed gas source: air source pressure ≥0.6 Mpa

2. ground bearing ≥500 kg/㎡.

3. Laboratory: The entire laboratory must have a ventilation system to discharge the smoke leaked during the test; the lighting is good, and it is convenient to watch the operating equipment.

4. The passage of the laboratory should be convenient to transport batteries and related transportation vehicles. People can be evacuated in time when a special emergency situation occurs.

5. laboratory should be equipped with corresponding fire fighting facilities to facilitate the use of its fire fighting tools.

6. ambient temperature: room temperature -35℃

7. Environmental Humidity :85% R.H ≤
