PRODUCTS DETAILS

10KV indoor high-voltage current transformer LA-10 semi-enclosed wall-type transformer, transformer, also known as instrument transformer, is a general term for current transformer and voltage transformer. It can turn high voltage into low voltage and large current into small current for measurement or protection systems. Its function is mainly to convert high voltage or high current into standard low voltage (100V) or standard low current (5A or 1A, all refer to the rated value) in proportion, so as to realize the standardization and small size of measuring instruments, protection equipment and automatic control equipment. change. At the same time, the transformer can also be used to isolate high-voltage systems to ensure the safety of personnel and equipment. In the power supply line, the current difference is from a few amperes to tens of thousands of amperes, and the voltage difference is from a few volts to several million volts. The current and voltage in the line are relatively high, such as direct measurement is very dangerous. In order to facilitate the measurement of the secondary instrument, it needs to be converted into a relatively uniform current and voltage, and the transformer is used to play the role of transformer transformation and electrical isolation.Technical parameters of LA-10Q current transformer 1. Rated insulation level of LA-10Q current transformer: 12/42/75kV 2. Rated secondary current: 5A 3. The rated primary current, accuracy class combination, rated output and rated dynamic and thermal stable current are shown in the table 4. Pollution level: The products in all working conditions meet the requirements of level II pollution. 参数4 规格_看图王(1) 形象1. Structural aspects The product adopts the through-wall epoxy resin casting insulation design, which can be divided into three types: single-turn type, multi-turn type and bus-bar type, which can be applied to the needs of various products. 2. Insulation level LA-10Q current transformer adopts high-performance imported electronic components, insulation level: 12/42/75kV, reaching the national standard. 3. Main role LA-10Q current transformer is mainly used for electric energy measurement, current measurement and relay protection. Working principle of current transformer: LA-10Q current transformer is based on the principle of electromagnetic induction. A current transformer consists of a closed iron core and windings. Its primary winding has a small number of turns, and it is connected in series in the line of the current to be measured, so all the current of the line often flows through it. When working, its secondary circuit is always closed, so the impedance of the series coil of the measuring instrument and the protection circuit is very small, and the working state of the current transformer is close to a short circuit.Normal working/installation conditions 1. Installation sites: Indoor 2. Ambient temperature : (-5~40)ºC 3. Ambient humidity: ≤80% 4. Altitude: ≤1000m 5. Atmospheric conditions: no serious impurity in the atmosphere. Ordering instructions: When the customer ordering, must provide the following information: 1product model and Install the bus width; 2, current ratio; 3, rated output, and the corresponding accurate level; 4, if you have special requirements, can be customized consultation with the manufacturer.
