The product is compact in structure, versatile, easy to use and stable in performance. It is particularly convenient for users to detect the insulation performance of various electrical equipments at the scene. There are three types of AC, AC and DC, and AC series. The unique structure of the symmetric octagonal shell with axisymmetric symmetry; can output double high pressure. The oil level in the fuel tank is lower than the tank edge, avoiding oil leakage. Terminals are on the cover to avoid collisions and improve mechanical and electrical performance. It has the characteristics of compact structure, stable electrical performance, sufficient capacity, small size, light weight, convenient use and maintenance, etc.
Precautions:
1. When doing high-pressure tests, it must be attended by 2 or more people, and clear division of labor should be done to clarify the contact method between each other. And there are special people to monitor the safety of the scene and observe the test status of the sample;
2. The transformer and control box should have reliable grounding;
3. During the test, the boosting speed must not be too fast, and sudden full-voltage power-on or power-off must not be allowed.
4. In the process of step-up or pressure test, if any of the following abnormalities are found, immediately step down the pressure, cut off the power supply, stop the test, and check the cause before doing the test.
(1) The voltmeter pointer swings greatly;
(2) Insulation burned odors and smoke were found;
(3) There are abnormal sounds in the tested product;
5. During the test, if the sample is short-circuited or breakdown, the over-current relay in the control box will work. At this time, the regulator will be returned to zero position and the power supply will be cut off before removing the sample;
6. When conducting capacitance test or DC high-pressure leakage test, after the test is completed, reduce the voltage regulator to zero and cut off the power. Then, discharge the high-voltage terminal of the test sample or capacitor to the ground with the discharge rod to avoid The potential remaining in the capacitor is at risk of electric shock.
The function of the crank-connecting rod mechanism of Car Engine System is to provide a place for combustion, which changes the expansion pressure of the gas acting on the top of the piston after burning the fuel into the torque of the crankshaft rotation, and continuously outputs power. It is generally composed of three parts: body block, piston connecting rod group and crankshaft flywheel group.
The function of the crank-connecting rod mechanism is to provide a place for combustion, which changes the expansion pressure of the gas acting on the top of the piston after burning the fuel into the torque of the crankshaft rotation, and continuously outputs power. Crank and connecting rod mechanism is the main moving part for the Car Engine to realize the working cycle and complete the energy conversion. In the working stroke, it converts the reciprocating motion of the thermal piston produced by fuel system combustion and the rotation of the crankshaft into mechanical energy and outputs power to the outside world; in other strokes, it relies on the rotating inertia of the crank and the flywheel to drive the piston up and down through the connecting rod, creating conditions for the next work.
