the electric flow will leak into the earth along the installed grounding wires, so as to achieve the purpose of safety, otherwise it will have an adverse impact on life safety.Then clamp the branch pipe with your thumb, clearly put forward the glass test tube, rotate and release the oil in the tube to clean the sampling tube, carry out it twice, and then draw the oil sample.Kamernitsky,Once the insulation material of electrical equipment is overheated, the surrounding gas will cause a kind of odor. This kind of odor can be sniffed out by normal patrol staff. When you smell such odor during normal inspection, you should carefully inspect the equipment and parts until you find out the cause.In relay protection dry-type transformer, the disconnection of the fault point is related to each other. In a word,The insulating layer shaft and the connecting articles between the bell jar and the core shall be removed. If it is a hanging bell inspection it will affect the whole power circuitAbakaliki, the oil shall be pumped into the bottom of the bell jar before the bell jar can be removed.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, 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.Analysis of common faults of oil immersed transformer:

When we apply oil immersed transformer, we all know that it works with the help of oil. What if the oil immersed transformer is on fire? What countermeasures should we do?Transformer manufacturers said that at this stage, China's energy-saving distribution transformer market is relatively scattered, coupled with the constraints of factors such as low threshold in the field, uneven companies lack of evaluation and specifications, and inadequate technical innovation, resulting in slow marketing of energy-saving transformers.Oil leakage of heat pipe radiatorLet's see,When we apply oil immersed transformer, we all know that it works with the help of oil. What if the oil immersed transformer is on fire? What countermeasures should we do?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:In terms of the place of use, dry-type transformers are mostly used in & ldquo; Fireproof and explosion-proof type & rdquo; It is easy to use in large and medium-sized engineering buildings and multi-storey buildings; The oil immersed transformer because of & ldquo; Accident & rdquo; There is likely to be oil or leakage after fire,KamernitskyHow much is the transformer, and most application places leading to fire accidents are easy to choose in large and medium-sized engineering buildings and multi-storey buildings;

Sound, causing short circuit obstruction. If not handled properly, it will cause great damage.Customer first,During no-load test run, the transformer shall be connected with the working voltage from the switching power supply side, and then make the working voltage impulse closing.The rate of transformer is: n = P / pxo%, the rate is very large. Therefore when the copper loss of transformer is equivalent to iron loss, the load of transformer is: = P / PK. Fully consider the active power loss caused by reactive power in the system software during transformer operation. The load adjustment is: it can be seen from the calculation of load formula that the large rate of transformer does not occur when the load is full, Generally, it is about %, but when selecting the transformer capacity,KamernitskySubstation transformer, we should select effective transformers according to the load condition and load, the calculation of data in the whole process of oil immersed transformer wave has long had results. Only effective selection of calculation entity models and methods is needed, the accuracy of calculation conclusions can meet the needs of architectural design, and scientific and reasonable data method is selected, Not only can the current distribution of the oil immersed transformer be clearly defined in the development stage, but also the winding and other structures of the oil immersed transformer can be effectively arranged and distributed in a certain scope, which greatly facilitates the design scheme of the oil immersed transformer and ensures the stability of operation.Kamernitsky,The switching power supply lacks one phase of power;The first step of the whole wave process calculation is to calculate the basic parameters of the Internet such as inductance, 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.Sound insulation treatment of main engine room the key to sound insulation treatment of dry-type transformer room is to start from three levels: window, ventilation and air exchange port and road surface, and apply sound insulation window, silencing cylinder, floating concrete floor damping pad and other sound insulation and noise reduction commodities to achieve sound insulation effect.
