What is a protective relay? Answer: It can reflect the failure or abnormal operation of electrical equipment in the power system, and act on the device that trips the switch or sends out a signal. What are the commonly used relays? A: Current Relay, Voltage Relay, Signal ...

21. What does the workplace have to meet for high-voltage electrical appliances? Answer: A. Rated voltage, B. Maximum working voltage, C. Rated current, D. Rated short-circuit interrupting current, E. Short-time withstand current and peak withstand current. 22. What are the basic requirements for a high-voltage circuit breaker? Answer: A work ...

1. Flashover fault: The industrial control cable is in a good insulation state at low voltage and will not have a fault. However, as long as the voltage value rises to a certain range, or a certain voltage continues to rise after a period of time, then it will instantly break through the insulator and cause flashover fault. 2. Long-term ...

1. Look at the packaging, the wires of the national standard are often better, neat, and have a sense of quality when you hold them. 2. To open the package and take a look at the wires inside, the wire requirements of the national standard wire 1.5——-6 square are required to be skin thickness (insulation thickness) is 0.7mm, and too thick is non-standard.

One. The nature is different Distribution box: There is a large amount of parameter data in the distribution box. It generally constitutes a low-voltage distribution box. Control cabinet: The control cabinet is to assemble the switch cabinet, measuring instruments, protection devices and auxiliary equipment in a closed or semi-enclosed metal cabinet or screen according to the requirements of electrical wiring.

1. Safety: As the carrier of electrical equipment, the outdoor cabinet must have excellent structural design, solid materials, and firm bottom fixation to meet the requirements of strong typhoons, strong rainstorms, and even strong earthquakes. At the same time, the cabinet should have anti-leakage, anti-short circuit, anti-cut and other requirements. 2. Rainproof and dustproof ...

First, the assembly process The assembly process is the guarantee of the assembly work, because only the assembly according to the process can ensure the quality of the assembly work. The process is the standard and requirement of assembly, and only the assembly according to the process can ensure the safety of assembly. However, before the assembly, the technical ...

1. a rack Rack: Installed in a standard cabinet, it is a functional server, so the standard cabinet is also called a "19-inch" rack. Rack is a more professional academic term, and most of the current policy documents mention "rack", and clarify the indicators such as single rack power and average shelf rate ...
