Abstract
The utility model relates to a reactive power compensation device with temperature control function, which is composed of a power switch (2), current transformers (3), fuses (4), fling-cut switches (5), protection devices (6), reactors (7), capacitors (8) and a fan (11), wherein the power switch(2), the current transformers (3), the fuses (4), the fling-cut switches (5), the protection devices (6), the reactors (7), the capacitors (8) and the fan (11) are all arranged in a cabinet body (1). The reactive power compensation device with temperature control function is characterized in that the cabinet body (1) is further provided with a temperature detecting probe (9) and a temperature control signal processor (10), and the temperature detecting probe (9), the temperature signal processor (10) and the fan (11) form a fan automatic on-off control circuit. By adding the fan on-off control circuit along with temperature control in the cabinet body, the utility model realizes the function that the fan changes with temperature in the cabinet to be on-off automatically, meets requirements of all devices in the cabinet to operating environments, and simultaneously avoids high energy-consuming waste and motor loss caused by long-term non-stop running of the fan.
Description
Technical field
The utility model relates to a kind of reactive power compensator, especially a kind of reactive power compensator of function of temperature control.
Background technology
Reactive power compensator is the electric equipment that must use in the power supply circuits system, reactive power compensator in the use often causes the cabinet internal temperature to raise because of the heating of electric capacity and reactor, make the heat dissipation environment variation, shortened the useful life of capacitor, reactor, failure rate increases.In order to address the above problem, method commonly used is to increase a cooling blower in cabinet, and the reactive power compensator in the running is in the air draft operational environment all the time, reaches the generation of avoiding electric capacity and reactor heating phenomenon.Obviously this form that allows the cooling blower personal attendant machine time turn round not only can cause the increase of whole system power consumption, and the difficult appearance of avoiding the cooling blower faults itself.In case breaking down, blower fan still can influence the operate as normal of reactive power compensator.
The utility model content
The purpose of the present utility model: be intended to propose a kind of reactive power compensator of function of temperature control, the heat dissipation environment when improving equipment operation in the cabinet had both guaranteed the service life of capacitor and reactor simultaneously blower fan can normally to be moved for a long time.
The reactive power compensator of this function of temperature control; form by mains switch, current transformer, fuse, fling-cut switch, protective device, reactor, capacitor and the blower fan be located in the cabinet; it is characterized in that: also be provided with temperature detection probe and temperature control signals processor in the described cabinet in addition, and form blower fan automatic open close control circuit by this temperature detection probe, temperature control signals processor and blower fan.
The reactive power compensator of this function of temperature control that proposes according to above technical scheme, because one that sets up in cabinet with temperature controlled blower fan keying control circuit, realized that blower fan changes and the automatic open close function with in-cabinet temperature, both guarantee all components and parts in the cabinet to the requirement of operational environment, also avoided the high energy consumption waste that the running that do not stop for a long time of blower fan brings and the loss of motor itself simultaneously.

Embodiment
The reactive power compensator of this function of temperature control as shown in the figure, it is a kind of improvement to existing congenerous reactive power compensator.The reactive power compensator of this function of temperature control; form by mains switch 2, current transformer 3, fuse 4, fling-cut switch 5, protective device 6, reactor 7, capacitor 8 and the blower fan 11 be located in the cabinet 1; it is characterized in that: also be provided with temperature detection probe 9 and temperature control signals processor 10 in the described cabinet 1 in addition; and form blower fan automatic open close control circuit by this temperature detection probe 9, temperature control signals processor 10 and blower fan 11, temperature control signals processor 10 is made of control unit switching signal box control unit sub-gate signal and contactor.
In the use: determine the design temperature of the best effort environment that electronic devices and components allowed in the cabinets by temperature control signals processor 10 according to capacitor 8, reactor 7, and by temperature detection probe 9 as temperature sensor.When in case ambient temperature surpasses design temperature in the cabinet, the blower fan 11 that controlled by temperature control signals processor 10 starts, enters aeration-cooling operating state automatically, and when in-cabinet temperature was lower than design temperature, temperature detection probe 9 can in time send signal to temperature control signals processor 10 again shut down blower fan 11.
Claims (1)
1, a kind of reactive power compensator of function of temperature control; form by mains switch (2), current transformer (3), fuse (4), fling-cut switch (5), protective device (6), reactor (7), capacitor (8) and the blower fan (11) be located in the cabinet (1); it is characterized in that: also be provided with temperature detection probe (9) and temperature control signals processor (10) in the described cabinet (1) in addition, and form blower fan automatic open close control circuit by this temperature detection probe (9), temperature control signals processor (10) and blower fan (11).
