Product Overview
When circuit grounds, CT could senses zero-sequence grounding current. To be equiped with relay protector or signal devices, it help device components act for the purpose of protecting or monitoring circuit.
MRD-L series zero-sequence CT is a kind of cable type, using ABS engineering plastics as casing, poured by resin. With beautiful appearance, good hermeticness, high insulation, high sensitivitym, good linearity, easy installation and wide application, it is not only suitable to magnetic relay, but also to electronics and mico-computer devices. CT type is determined by the operation way of user.(Neutral ground, unground,ground by high-resistance,low resistance or arc suprression coil.)
MRD-L series zero-sequence CT core is made of ZH120-130 cold rolled silicon steel sheet imported from Japan with advantages of smooth surface, constant thickness, good conductivity, strong sensitivity to magnetizing, accuracy and stability.
Inner Diameter (select site cable and inner diameter of zero-sequence CT), See table1

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 .

- Q: Electric power automation equipment
- Power grid dispatching automation, power system analysis and control, power electronics, power market, distribution automation,
- Q: What are the characteristics of the grounding of the power system and equipment?
- According to the use and nature of grounding, it can be divided into "working grounding" and "security grounding".
- Q: Power equipment sales process, the customer asked the most questions thank you
- 3, the component parts of the device, which is the core component of the device, to master the working principle of the device oh;4, after-sales service problems, technical introduction of after-sales service;5, price, product prices and other brand products at what level;
- Q: What is the specific name of the double name of the equipment in the electric work sheet? Know please enlighten me.It would be better if you had a sample ticket.
- Such as: 307DL. The device name is on the circuit breaker, numbered 307DL, together they should write off on the line: circuit breaker 307DL
- Q: How to strengthen the management of electric power information communication equipment
- 2 equipment based information is not complete. In the past is mainly due to the importance of equipment installation and use of the process to ignore the basic data, no serious equipment complete basic data collection and sorting, resulting in a lack of power information communication equipment basic information.3 equipment inspection is not in place. Regular inspection of power communication equipment can clear the health status of the equipment, and can detect the problems or defects in the equipment. At present, the problems existing in the inspection work of the electric power communication equipment are as follows: (1) there is not a reasonable equipment inspection cycle. (2) in the process of inspection and inspection of the equipment does not follow a certain inspection process. (3) during the inspection process, the equipment running state inspection is ignored, and the inspection of the equipment room condition, water proof and fire prevention ability is ignored. (4) the inspection of the sanitation and environmental temperature of power communication equipment is ignored.
- Q: What are the technical measures to ensure the safety of the power line equipment?
- 5 hanging sign and installing fence (fence).These are the contents of safety regulations (line part)
- Q: What is the importance of annual maintenance of electrical equipment? What harm does not do? As detailed, urgently!
- Two, power equipment testing overviewElectrical equipment preventive testing refers to the equipment has been put into operation according to the stated experimental conditions (test equipment, such as the provisions of the environmental conditions, test methods and test voltage etc.), regularly check the test items, test period ofOr test to find out the hidden trouble of the electric equipment in operation, prevent the accident or the damage of the electric equipment. It is an important measure to judge whether the power equipment can be put into operation and ensure the safe operation.With the rapid development of social economy, the rapid development of science and technology, the range of power equipment testing, equipment and technology are advancing with the times. A set of equipment "health index" including its electrical characteristics and mechanical characteristics of the two part of the contents of the groupAs a result, and can not get the power equipment in the power of the electrical characteristics of the "health value" this problem has been plagued by power users for many years. The emergence of a new condition monitoring technology solves this problem. Not only extends the powerThe concept of equipment testing, but also to fill the blind spot in the field of power equipment testing. The conventional power outage detection and monitoring technology complement each other, to provide a full range of data support for the reliable operation of power equipment.
- Q: What specific enterprises and units are used to test the power of the equipment ah
- Electric Power Bureau must be used to detect classes, each project must be checked by the Electricity Industry Bureau
- 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
- Power equipment classification:1 the sequence of electric power in power system can be divided intoPower generating equipment, power generation equipment, power transmission equipment and electric equipment2 the main role of the power system can be divided intoPrimary equipment, two equipment
- Q: What is the redundancy of electrical equipment
- Redundancy is a part of the system that is repeatedly configured. When the system is in trouble, the redundant components are involved in the work of the faulty components, thereby reducing the failure time of the system.
