Q:How to handle the qualification test, what kind of power equipment

To submit the application form for the installation of power equipment (repair, test)";

Q:Reactive power compensation methods commonly used in power equipment

The centralized compensation is to set up the reactive power compensation device in the power distribution room to compensate the reactive power in the region. Due to the introduction of several kinds of compensation sampling is set at the point of measurement, so you can minimize the interest rate generated electricity.In the professional field and transmission line compensation (high and low), furnace low-pressure grid compensation, flameproof compensation device etc..

Q:What is the good rate of equipment determined by the rating of substation equipment

With China's state-owned enterprises economic autonomy to the enterprise, the equipment management should also be extended: the demand rate of sound equipment, ensure the normal operation of equipment is the most important management goal, extended to the assessment of fixed assets created by the economic benefits

Q:What equipment is necessary on the list of electrical engineering equipment?

MSXB-F-75kVA/720kV frequency conversion resonance withstand voltage test device, MSDBF-30kVA multi frequency induction withstand voltage test device,

Q:What is the importance of annual maintenance of electrical equipment? What harm does not do? As detailed, urgently!

The necessity of power equipment testingPower equipment is the hub and channel in the transmission and distribution network, in the course of the use of equipment will be aging, disrepair, hidden trouble, etc.. However, these situations can not be ruled out by the eyes of the people, the staff of the experience, it is necessary to detect the special power equipment to check out these security risks and the organization of human resources in a timely manner to exclude.In the operation of electric power, the safety of electric power has always been a chord of the electric power. Power equipment testing is actually played a role in prevention and detection of hidden dangers. So it is very important to detect the electric equipment (i.e., the preventive test of electric equipment).

Q:Power equipment sales process, the customer asked the most questions thank you

In order to make electricity sales, electricity is to master the basic skills, to see more electrical and electronic, electric power system, plant power supply and distribution aspects of the books, only solid basic skills can be handy, you should at least master will sell the product knowledge, understand.

Q:1, common measurement and control cabinet, what is the common measurement and control cabinet? What signals are measured? High voltage side (10kV and above) have the corresponding relay protection device, regardless of the panel or on the spot, will not be on the public measurement and control cabinet; the so-called public measurement and control cabinet is measuring what? Low voltage measurement and control? Or what, for example, thank you (power generation, power supply and distribution does not matter, can speak on the line)2, network equipment cabinet, I probably can understand, is from the equipment from various communication signals collected by the communication management unit, the output signal of Ethernet, this cabinet is the main communication management machine and switch is?3, how to locate the remote communication cabinets? What is the main role? What are the main equipment?4, why do we usually need GPS time device, what is the significance? What will happen if there is no?

The common measurement and control cabinet are generally some common control signals such as AC / DC screen, knife position, device power loss and telemetry some voltage and current value, there are no specific remote control, measurement and control device of equipment access to public control

Q:What are the two devices in the power system

Connect the two device circuit, called the two line. In the two line of DC is generally used for communication detection equipment, such as PABX, PDH, MUX, generally for 48V DC power supply, AC line for AC equipment use

Q:The company has a number of power equipment to be exported, need to go through the sea, the technical requirements of three, I would like to ask what is the three here? How to check whether the complete sets of components used to do three treatment? Please exhibitions, grateful!

The complete set of power distribution equipment is a complete set of equipment supplied by the manufacturer. The electric main circuit is divided into a plurality of units, each unit is a circuit, and the circuit breaker, the knife gate, the current transformer and the voltage transformer of each unit are connected

Q:Private enterprises must be free transfer of power facilities

The new user electrical facilities investment, after the investment asset is transferred to the power supply enterprise, according to the need for "business rules", the actual state of electricity contribution, interface division, maintenance management ability, after consultation by both parties to determine.
