Specification and model of 3kv6kv10kv high voltage capacitor compensation cabinet

 
  Parallel capacitor compensation cabinet has many uses in power system
By connecting them line to line, they are used as a source of reactive power
Utilities also connect capacitors in series to reduce its impedance with long lines
This is particularly common at the transmission level, because the length of the transmission line is only a few hundred kilometers
However, this paper will generally discuss the shunt capacitor compensation cabinet

Parallel capacitor compensation cabinet is usually called “ Power factor correction capacitor compensation cabinet ”, Although they also have other functions and provide multiple benefits, this will be discussed in subsequent paragraphs
Moreover, they can be used for all voltage levels from end-user use to EHV

Parallel capacitor compensation cabinet, whether used for power factor correction in the customer's location or voltage control in the distribution system, can greatly change the change of system impedance with frequency
Capacitance compensation cabinet will not produce harmonics, but sometimes serious harmonic distortion can be attributed to the existence of capacitance compensation cabinet

The shunt capacitor compensation cabinet at the end of the feeder will cause the voltage along the feeder to change gradually
Ideally, the voltage rise percentage of the capacitor compensation cabinet is zero at no-load and rises to max at full load
However, for the shunt capacitor compensation cabinet, the percentage of voltage rise is basically independent of the load
Therefore, automatic switching is usually used to provide the desired regulation under high load, but to prevent excessive voltage under low load
In addition, the switch of capacitance compensation cabinet may cause transient overvoltage inside the customer's facility

Parallel capacitor compensation cabinet – Parallel capacitance compensation cabinet is a capacitance compensation cabinet in parallel with the line
It is installed in the receiving end substation, distribution substation and exchange substation
The shunt capacitor compensation cabinet injects the reactive volt ampere into the line
It is placed in the three-phase library
The basic principle of power factor improvement is to connect a device that parallels the lead current with the inductive load to offset the influence of the lag current
Capacitor is such a device

Measures to improve power factor
There are many ways to improve the power factor, which are mainly divided into two categories, namely, to improve the natural power factor and to improve the power factor by manual compensation
The so-called improvement of natural power factor means that no compensation equipment is added, and measures are taken to improve the working condition of the equipment, so as to reduce the reactive power of electrical equipment and improve the power factor
The so-called manual compensation to improve the power factor generally means that factories and enterprises often use parallel capacitor compensation cabinets to compensate reactive power
