High-voltage switch dynamic characteristics tester adopts high stability device

The main performance and features of the instrument
(1) The instrument uses a high stability device. Floating, large-area, digital filtering and other anti-jamming technologies.
(2) The instrument is equipped with two types of displacement sensors, which are suitable for detecting high-voltage circuit breakers with different distances, speeds, and precision requirements. After different sensors are inserted, the instrument will automatically recognize them. The instrument can automatically recognize the operation of the high voltage circuit breaker (separation) gate and the reclosing operation, and automatically collect all kinds of data after the operation. The measurement calculation process is done automatically by the CPU.
(3) The instrument has automatic recognition ability and strong self-protection function for the wiring error of the high-voltage circuit breaker during measurement and the wrong instruction and unsuccessful operation.
(4) The instrument's sequence of coincident (sub-) gates and the actual closing time of each fracture shall be displayed. It provides the basis for repairing and debugging the three phases of the high-voltage circuit breaker in different phases and different phases of the same phase. The data is automatically displayed with 0.1 milliseconds of data.
(5) The instrument measures the stroke and overtravel of the moving contact. As long as the sensor is installed on the fracture of any phase of the high voltage circuit breaker, the trip and overtravel data of each three-phase fracture can be measured and calculated at the same time. The measurement accuracy is 1% second meters.

Calcium Carbonate

According to the different production methods of calcium carbonate, calcium carbonate can be divided into Heavy Calcium Carbonate, light calcium carbonate, colloidal calcium carbonate and crystalline calcium carbonate. White solid, tasteless and odorless. There are two forms of amorphous and crystalline. The crystal type can be divided into orthorhombic crystal system and hexagonal crystal system, which are columnar or diamond-shaped.

Calcium carbonate is widely used in filling polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), acrylonitrile butadiene-styrene copolymer (ABS) and other resins. The addition of calcium carbonate has a certain effect on improving certain properties of plastic products and expanding their application range. In plastic processing, they can reduce resin shrinkage, improve rheology, and control viscosity. It can also play the following roles:
(1) Improve the dimensional stability of plastic products;
(2) Improve the hardness and rigidity of plastic products;
(3) Improve plastic processing performance;
(4) Improve the heat resistance of plastic products;
(5) Improve the astigmatism of plastics;
(6) It can make the product have some special properties;
(7) Reduce the cost of plastic products.
