Abstract
Frequency converter disclosed by the utility model cools down motor control assembly, and including the use of the cooling motor of mains-supplied, cooling motor is connected with relay, and cooling motor is also connected with temperature sensor and controller in turn, and controller is connected with relay.The frequency converter cooling motor control assembly of the utility model solves the problems, such as existing cooling motor by inverter supply and is worked at the same time with frequency converter.The frequency converter cooling motor control assembly of the utility model is that cooling motor is powered using independent power supply system; and by the way that cooling motor work is just driven after collecting temperature when temperature is higher; reduce the unnecessary working time of cooling motor in this way; its service life is extended, the trouble free service of cooling motor is also further ensured by the earth leakage protective device of installation.
Description
Technical field
The utility model belongs to control technical field of electric appliances, and in particular to a kind of frequency converter cooling motor control assembly.
Background technology
Frequency converter is especially important for the power supply of system as electric control appliance, can be produced in the frequency converter course of work
Raw amount of heat, therefore its internal cooling motor driving water pump of setting carries out cooling and heat dissipation, cooling motor generally uses frequency converter
Internal transformer is directly powered, but this power supply mode has the following problems：
1. as long as frequency converter power transmission, no matter frequency converter box interior temperature height, cooling motor can all work, long-term in this way
Work influence cools down the service life of motor；
2. transformer lacks necessary protection system directly to cooling motor power supply；
3. cooling electric system is frequency converter auxiliary system, directly by inverter supply, when cooling motor when something goes wrong,
It can influence frequency converter work.
Utility model content
The purpose of this utility model is to provide a kind of frequency converters to cool down motor control assembly, solves existing cooling electricity
The problem of machine relies on inverter supply and is worked at the same time with frequency converter.
Technical solution used by the utility model is：Frequency converter cools down motor control assembly, including the use of mains-supplied
Cooling motor, cooling motor is connected with relay, and cooling motor is also connected with temperature sensor and controller, controller in turn
It is connected with relay.
The utility model is also characterized by
Further include 12V regulated power supplies, device power supply in order to control after 12V regulated power supplies are depressured by Voltage stabilizing module.
The model AT89C51 of controller.
The model LM7805 of Voltage stabilizing module.
Controller drives relay work by drive module.
The model UNL2003 of drive module.
Cooling motor is also associated with earth leakage protective device.
The utility model has the beneficial effects that：The frequency converter cooling motor control assembly of the utility model solves existing
The problem of cooling motor relies on inverter supply and is worked at the same time with frequency converter.The frequency converter of the utility model cools down motor control
Device processed is cooling motor power supply using independent power supply system, and cold by just being driven after collecting temperature when temperature is higher
But motor works, and reduces the unnecessary working time of cooling motor in this way, extends its service life, also pass through the leakage of installation
Non-electricity protector further ensures the trouble free service of cooling motor.
Description of the drawings
Fig. 1 is the structural schematic diagram of the frequency converter cooling motor control assembly of the utility model.

Specific implementation mode
The utility model is described in detail with reference to the accompanying drawings and detailed description.
The structure of frequency converter cooling motor control assembly provided by the utility model including the use of alternating current as shown in Figure 1, supply
The cooling motor 1 of electricity, cooling motor 1 are connected with relay 2, and cooling motor 1 is also connected with temperature sensor 3 and controller in turn
4, controller 4 is connected with relay 2.
Further include 12V regulated power supplies 5, the power supply of device 4 in order to control after 12V regulated power supplies 5 are depressured by Voltage stabilizing module 6.
The model AT89C51 of controller 4.
The model LM7805 of Voltage stabilizing module 6.
Controller 4 drives relay 2 to work by drive module 7.
The model UNL2003 of drive module 7.
Cooling motor 1 is also associated with earth leakage protective device 8.
The voltage of 12V regulated power supplies 5 is passed through model by the frequency converter cooling motor control assembly of the utility model
The power supply of device 4,3 real-time monitoring of environmental temperature of temperature sensor are uploaded to control in order to control after the Voltage stabilizing module 6 of LM7805 chips is depressured
Device 4 processed, then drive module 7 and then the driving conducting of relay 2 when controller 4 confirms that environment temperature reaches set temperature, to
So that cooling motor 1 is cooled down using alternating current work, when environment temperature reduces in frequency converter, controller 4 controls relay 2
Cooling motor 1 is set to be stopped.And when electric leakage or other unsafe conditions occur, then cooling is made by earth leakage protective device 8
Motor 1 thoroughly powers off.
