PetrikovOil immersed transformer oil storage tankHow to choose the medium for cooling

The oil in the machinery and equipment of the oil storage tank shall generally stand for more than h before sampling; it is not necessary to stand when sampling on the running power transformer.The clock expression is used to indicate the phase difference correlation of the working voltage of the secondary side line. The phasor of the working voltage of the primary side line is used as the minute hand, the fixed finger is at o'clock,There is a magnetic induction line crossing in the transformer core, it is called vortex. The existence of vortex makes the transformer core hot and consumes kinetic energy. This kind of loss is called vortex loss.Oil leakage of porcelain pot and laminated glass oil level gaugeKusA,Petrikov10kV distribution transformer,Power transformers are used in all walks of lifeThe long-term overload of power transformer will slowly cause the scalding and insulation aging of solenoid coil, resulting in short circuit between coils, two-color short circuit or short circuit on the ground, resulting in the ignition of power transformer. Therefore, the insulation compressive strength of power transformer shall be tested before installation and operation, and overload is not allowed in the whole process of operation.How much is the power transformer

When the transformer is out of phase, if the second phase is blocked, there is still no sound when the second phase is sent, and there is sound when the third phase is sent; If the third phase is blocked, the sound will not change, as in the case of the second phase. There are three reasons for phase deficiency:The selection shall be carried out according to the load characteristics of power. There are many types of power loads. Different dry-type transformers shall be used for different power loads. If the standard impulse level of power load is less than kV, class H dry-type transformers shall be used. If the standard impulse level of power load exceeds kV, epoxy resin adhesive shall be used to pour dry-type transformers.The power transformer belongs to relatively durable electrical equipment, and we can't neglect it in daily application. The common problems of power transformer conductor power transformer winding and power transformer tapping power switch are analyzed below:Promotion, and the transformer will turn to all normal operation.The first step of the whole wave process calculation is to calculate the basic parameters of the Internet such as inductance the main body and accessories of the transformer are all normal, capacitance and resistor. The accuracy of those basic parameters does great harm to the calculation results of the whole wave process. For the inductance calculation, the good model is the solid model of infinite transformer core column, but there are many calculation methods.A zero line of the power transformer is connected with the working equipment. Since the voltage formed by the server during operation will be sent to the power transformer along with the cable, the power transformer will be transported and sent to the power consuming machines and equipment. What is the zero line of the actual power transformer? Let's introduce it to us.

When the transformer is out of phase, if the second phase is blocked, there is still no sound when the second phase is sent, and there is sound when the third phase is sent; If the third phase is blocked,PetrikovTransformer box type transformer, the sound will not change, as in the case of the second phase. There are three reasons for phase deficiency:Inspection basis,Sound, causing short circuit obstruction. If not handled properly, it will cause great damage.In order to better avoid overvoltage damage, a group of overvoltage maintenance high-voltage Arresters (such as ycs active zinc oxide high-voltage arresters) shall be refitted at the working voltage bus duct side of dry-type transformer.Causes of fire in power transformerPetrikov,Under normal conditions, the actual operation of the oil immersed transformer shall be undertaken by the on-site operation and maintenance management staff. Within one week of grid connected operation,PetrikovDry type transformer industry market, the operation and maintenance management staff shall improve the safety inspection range of the transformer, and immediately communicate and contact with the on-site project staff in case of any problems, so as to ensure the reliable and stable operation of machinery and equipment.(III) dry type transformers of KVA and below can be installed on poles. The distance between its bottom end and the road surface shall not be less than m; The distance between the electrified part and the road surface shall not be less than m.() the installation position of secondary commercial insurance of transformer on column and ground shall meet the following requirements: if there is an disconnector on the secondary side, it shall be installed between the disconnector and low-voltage composite insulator, or the circuit breaker shall be selected as the disconnector; If there is no disconnector on the secondary side, it shall be installed on both sides of the low-voltage composite insulator and the insulated cable jumper shall be connected to the insulated cable on both sides of the circuit breaker.
