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:What are the effects of frequency variation on power users and power systems?: As we all know, the asynchronous motor is widely used in industry. Its speed and output power are related to frequency. Changes in frequency, speed and power output of the motor is also changing, which seriously affected the quality of the product; modern industry, national defense and scientific research has been widely used in various electronic technology equipment, if the system frequency instability, affect the accuracy of these devices will be.

Q:Is there a warranty period for power equipment?: Therefore, every year there must be high and low voltage as well as the relevant leakage test, consistent with the standard that is to continue to use.

Q:The insulation level of the electrical equipment in the neutral grounding system shall be consideredA. phase voltage;The square root of 2 phase voltage B.;The square root of 3 phase voltage C..Great God in the end this election? I am very tangled!: According to the line voltage, the neutral grounding is star type connection, line voltage is 3 times the square root of the phase voltage, so the choice of C

Q:On the nameplate of the electrical equipment, what does ith UE ie mean?: Electrical equipment consists of two parts: power supply and power equipment. The power supply comprises a storage battery, a generator and a regulator thereof. The utility model comprises a starting system of an engine, an illumination, a signal, an instrument, etc., and also comprises an ignition system of the engine.

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!: As well as protection, control, measurement and other devices are assembled in a whole cabinet, there are a number of high-voltage switchgear in power plants, substations or power distribution equipment installed after the installation of the power plant is called a complete set of power distribution equipment.

Q:Electric power equipment includes what steam turbines are used in what areas of what companies need steam turbines: Power equipment including: boiler, steam turbine, pump, deaerator, condenser, generator and so on, from the impact of steam boiler turbine blade hot out of the turns, then drives the generator to rotate to generate electricity, in general, now in thermal power plant and a large Shipping Co to use steam turbine

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:The state of power system equipment is divided into four states: (4) maintenance status. Circuit breaker and isolating switch device in the open position, the circuit breaker can be divided, and the control switch, fuse (or switch) switch maintenance should be off line and on both sides of the grounding switch (or installed ground), and hung signs work.

Q:Recently went out to do the test, do not know the difference between the two tests: Is your company product acceptance test of customer delivery, in order to find new equipment in the design, manufacture, transportation and installation in the process of diagnosis is consistent with the risks, operational conditions, testing of new equipment.

Q:Maintenance of electrical equipment, security measures to ensure that what: 6, is strictly prohibited live moving, demolition, relocation and maintenance of electrical equipment and lines.7, all cables are not allowed to have a fire joint, tear, leakage phenomenon, such as cable break, should be used with equal effectiveness hot cold patch, allowed to send electricity.8, all electrical equipment is strictly prohibited fire operation, maintenance of electric equipment, should be properly protected, not smashed on the explosion-proof surface, ensure the explosion-proof surface finish and explosion-proof performance, and paint oil or vaseline to evenly.9, timely maintenance control, switch control must hit the "off" position, set off switch handle, and remove the clutch.
