Abstract
The utility model discloses a low voltage capacitance reactive power compensator junction box which belongs to a power grid control equipment component range. In the junction box, the capacitance reactive power compensator is formed by capacitance compensators, a switch and a low voltage fuse, wherein the capacitance compensators are connected and form a triangle; and the capacitance compensators are connected to the switch and the low voltage fuse. The capacitance reactive power compensator is connected to an input 315A circuit breaker of a power supply through a 125 A circuit breaker and is connected to an output terminal of a primary side system. Two output 160A circuit breakers are connected to the input 315A circuit breaker. The junction box of the utility model is suitable for being used under an alternating current 50Hz and a 660V nominal voltage, with large changes of load power, and in industries of electric power, an automobile, petroleum, a chemical industry, metallurgy, railway, a port, coal mine, an oil field and the like, wherein the industries have a high requirement to a voltage fluctuation and a power factor. Operation is convenient and the junction box is safe and reliable. A nominal voltage of a phase-shift capacitor is increased and the service life of a component is prolonged.
Description
Technical field
The utility model belongs to the components range of power grid control equipment, particularly a kind of low-voltage capacitance reactive-load compensator terminal box.
Background technology
At air-conditioning, illumination, during the nonlinear load operations such as the three-phase equipment that office equipment and industrial production are used, can produce a large amount of reactive loss and harmonic wave, these reactive loss and harmonic wave are mainly from range transformer, in system, the existence of a large amount of harmonic waves can cause a large amount of electric energy losses, can be to electric power, electronic equipment exerts an influence, when serious, also will cause equipment to move, even may form certain threat to whole system and even public electric wire net safe and reliable operation, the reactive power that general enterprises and institutions consume electrical network accounts for and consumes 50～90% of active power, if power factor is brought up to 0.95 left and right, reactive power consumption only occupies 30% left and right that merit consumes.Traditional voltage switch cabinet does not have reactive-load compensator, often local power grid is impacted, the utility model is designed to modular terminal box by low-voltage capacitance reactive-load compensator, reduced the input of power system reactive power, take reasonably idle and harness of harmonic wave can effectively improve the quality of power supply, the safe and stable operation of support equipment, can significantly save electric energy simultaneously.
Utility model content
The purpose of this utility model is there is no reactive-load compensator for traditional voltage switch cabinet, the deficiency often local power grid being impacted, a kind of capacitance reactive compensation device terminal box is provided, it is characterized in that, in terminal box, capacitance reactive compensation device is by connecting into leg-of-mutton capacitive compensator, connecting and composing with switch, low-tension fuse, and be connected by the input 315A circuit breaker of 125A circuit breaker and power supply, 315A circuit breaker is connected to the output of primary side system again through L1-L3 tri-line fuses; Export 160A circuit breaker with the two-way that also has that input 315A circuit breaker is connected.
The beneficial effects of the utility model are that the utility model is applicable to exchange 50Hz, rated voltage below 660V, bearing power changes greatly, the industries such as the electric power that voltage fluctuation and power factor are had higher requirements, automobile, oil, chemical industry, metallurgy, railway, harbour, colliery, oil field.Easy to operate, safe and reliable, improve phase shifting capacitor rated voltage, extend components and parts useful life.
