Quick Details

Place of Origin:	HeBei China (Mainland)	Brand Name:	CNBM	Model Number:
Over-voltage protection:	10KV 24KV 35KV

Specifications

resistance-capacitance protector is most advanced in the internally installed overvoltage protectors of vacuum switch cabinet

Over-voltage protection Combined Overvoltage Protector

Normal working terms
1.Environmental temperature: -40aa ~ +60aa;Rated frequency: 48Hz~ 62Hz
2.Altitude:< 2000m

Character

1. Maximum capacity, better limite voltage effect, more widely applicable scope, stronger tolerance , long lifespan

2. Voltage impact coefficient is 1, under the various kinds of electric voltage waveform, the voltage values are equal

3. With zinc oxide nonlinear resistors and discharge gap between the structure, make the two are complementary protected. The spark gap make the State-of-Charge of zinc oxide resistance to zero, Zinc oxide resistance nonlinear characteristics also make the spark gap action without free-wheeling in future, The spark gap no longer bear arcing tasks, and improve the service life of the product;

4. Four lines connect method, can be greatly reduce the voltage of phase, the reliability of the protection is greatly improved;

5. Valve plates and the spark gap assemble space, and mutual influence, discharge electrode is not easy to damp, be oxidated, make action value more stable and reliable.

6.Take overvoltage action techniques and fault automatically function , realize the device maintenance free, at the same time, to avoid the tedious work periodically, to solve the engineering and technical personnel to worry about the problems of the equipment safe running .

Supplier Assessment Reports are detailed on-line reports about the supplier's capabilities. It helps you get all the information you need to trade confidently with suppliers.

Q:Part of the rated voltage of the power equipment is marked 10.5kv, and this is similar to the label 10KV power equipment what is the difference?Consulted a lot of teachers, but it is said that this is the old and new two methods, I would like to ask what is the basis of this, it is best to have a national standard for reference: 4, the average rated voltageRegulations, average rated voltage is about 1.05 times the network voltage, and appropriate rounding

Q:What are the main interference sources of the two power system: Power system electromagnetic environment consists of one or two devices, of which there are a variety of electromagnetic disturbance and interaction, the current electric power system is developing towards higher voltage, higher capacity, power network is more intensive and more complex systems, more advanced equipment to the direction of development, to guide electromagnetic disturbance of power system more serious and complicated. On the other hand, the advanced power systems using more advanced automation and other electronic and computer control, measurement, communication and protection system, and solid state electronic based advanced equipment and system tolerance electromagnetic disturbance ability is weaker, more susceptible to electromagnetic environment.

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:Reactive power compensation methods commonly used in power equipment: For the operation of specific projects, the compensation can be divided into: in situ dispersion compensation and centralized compensation.In situ compensation is to set up a reactive power compensation device on the spot to compensate for a single device. However, the need for compensation equipment, large investment, maintenance management is not easy.

Q:What is the definition of abnormal equipment, equipment failure, equipment failure and equipment accident? From which power standard?: Accident: has occurred, resulting in loss of damage,Such as short circuit arc circuit breaker tripping, burning, scrap.

Q:What equipment are used in the power, can help to divide some of the details, as well as the type of equipment under the type of equipment: When drawing the main wiring diagram, the transformer, arrester, capacitor, neutral point equipment and carrier communication can be used to reflect the situation of power supply in normal and accident conditions. Electrical wiring is also known as the main electrical

Q:In order to ensure the normal operation of the power system and equipment to achieve a grounding: 4) repeat grounding: in the low voltage three-phase four wire system (380V/220V), which is directly grounded in the neutral point, in addition to the working connection at the power supply, it is necessary to re connect the ground at the other place of the zero line. To ensure the safety and reliability of the zero line. It is simply to say that one or more points on the zero line are grounded again.

Q:1 what is the power system and the power network? 2 what is the rated voltage of the electrical equipment? Why do the power system to use a variety of voltage levels? 3: The rated voltage of the electrical equipment is the working voltage standard designed by the designer.4, the power system uses a variety of voltage levels, on the one hand is the process of historical evolution, in 50s only 35KV, in 60s with 110KV, in 70s the establishment of the 220KV power grid, and later developed to 500KV and DC transmission. On the other hand, a higher voltage level is used to further the safety and economy of transmission. Of course, the retention of 35KV and 110KV, but also taking into account the economic costs of close range transmission.

Q:In what way is it confirmed that the destroyer is an electrical device? Identification or what.: Not yet installed agricultural low-voltage lighting circuit, not in the use of electrical equipment. Even if the person who took part in the erection of the wire, it will not cause harm to public safety, its behavior should be qualitative theft.

Q:How to handle the qualification test, what kind of power equipment: (a) legal person qualification and perfect organization; (two) the registered capital and net assets of 60 million yuan; (three) the last 3 years to bear the following first items listed, third project and second sub items listed in any one project, and the project quality: above 1 thousand and 330 volts voltage substation 2 or 220 thousand volt substation 5; more than 2 thousand and 330 volt overhead lines 300 kilometers or 220 thousand volt overhead line of 500 kilometers; more than 3 thousand and 220 volt cable line 80 kilometers or 100 meters above the level crossing tower crossing project 1.
