Abstract
Provided is an intelligent modular capacitor cabinet, which is composed of a cabinet body, a top beam, a cross beam, a horizontal busbar clamp, a horizontal busbar, a transfer busbar, an N-phase neutral busbar, a PE protection busbar, a gate capacitor, a current transformer, a fuse reverse switch, an indicator, a switch, a cover plate and the like. Being provided with an intelligent monitoring system and a self-repair system, the intelligent modular capacitor cabinet can not only diagnose a fault by itself to improve the protective measures, but also can repair itself to make the capacitor continue to run when it comes to a normal breakdown accident, thus further improving the quality of power supply. Meanwhile, the intelligent modular capacitor cabinet consumes less power, has no harmonic and is more energy-saving. In addition, resources can be saved, the energy consumption can be reduced, the environment can be protected, and green power can be built up for effectively controlling the line loss and improving power supply efficiency and voltage quality of a system.
Description
Technical field
The utility model relates to the capacitor box field of power supply grid, relates in particular to a kind of intelligent modularized capacitor box.
Background technology
At present, known capacitor box is one of visual plant in the electric power system, and capacitor box is to utilize the capacitive reactance of electric capacity to come the induction reactance of compensating inductance load, reduces reactive current, reaches energy-conservation effect.Utilize power factor meter to observe, by the quantity of switching capacitance, power factor reaches or near 1 o'clock, capacitor box was normal.Existing capacitor box can only have level to regulate, and can not carry out smooth adjustment; Improper ventilation is in case when the capacitor operating temperature is higher than 70 ℃, easily expand blast; Voltage characteristic is bad, and is poor to short-circuit stability, and residual charge is arranged after the excision; The reactive power compensation precision is low, easily affects compensation effect; The effect that the problems affect capacitor box such as the problem of the operational management difficulty of compensation condenser and capacitor safe operation does not come into one's own etc., and inner each component installation location design of the parameter capacitor box of existing each parts of capacitor box is reasonable not use.
Summary of the invention
The deficiency that the utility model exists for existing above problem, be strong control line loss, the power supplying efficiency of raising system and quality of voltage are effectively to reduce the power distribution room reactive power, improve power factor, guarantee taking full advantage of of active power, the utility model provides a kind of intelligentized intelligent modularized capacitor box.
The technical scheme that its technical problem that solves the utility model adopts is:
Intelligent modularized capacitor box is with intelligent monitor system and self-healing system, and not only tracing trouble voluntarily improves safeguard measure; and when running into normal breakdown accident; can self-healing, make capacitor can continue operation, further improved power supply quality.Simultaneously, its power consumption is little, and is without harmonic wave, more energy-conservation.Economize on resources, reduce energy consumption, protection of the environment, be strong control line loss, improve power supplying efficiency and the quality of voltage of system, Green electric power
Intelligent modularized capacitor box is by cabinet, and back timber, crossbeam, horizontal bus folder, horizontal bus, transfer bus, N phase neutral bus, electric capacity, current transformer, Fuse Type fall the compositions such as switch.
Improve the thermal capacity of conversion fitting, reduction is by a relatively large margin broadcast the additional temperature rise that part, cable end, space bar bring because the temperature rise of adaptor gives to connect.Moving, the Heat stability is good of bus flat placed type collating unit, the impact that can bear the 80/176kA short circuit current.Loop quantity as many as 22 times has taken into full account large single-machine capacity power plant, the industry automation Electrically operated gate (machine) such as petrochemical system group's needs.Being connected in the cable compartment of the utility model and external cable finished, and cable can pass in and out up and down.Zero sequence current mutual inductor is put in the cable compartment, makes installation and maintenance convenient.Same source power distribution system can be mated limiting short-circuit current by current limiting reactor, stablizes busbar voltage at certain numerical value, also can partly reduce the requirement to the components and parts short-circuit strength
The utility model is applicable to the distribution system of the industries such as power plant, oil, chemical industry, metallurgy, weaving, skyscraper.High in automated procedures such as big power station, petrochemical systems, require the place with computer interface, be that 50 (60) Hz, rated operational voltage are 380V (400), (600) as the three-phase alternating current frequency, rated current be 4000A and following send out, low-voltage complete electric installation that distribution, motor centralized control, reactive power compensation in the electric power system use
The beneficial effects of the utility model are:
1, cabinet adopts the local welding of 8MF cold-rolled forming section to assemble, and structural strength is high;
2, power supply quality is well improved, and economizes on resources, and reduces energy consumption, protection of the environment.
3, tracing trouble voluntarily improves safeguard measure, self-healing;
4, bus and outlet cable arrangements are reasonable, and reliability is high, and security performance is high.
