Description
Technical Field
The utility model relates to an electric field.
Background
Many electrical devices are installed in the electrical cabinet, and all the electrical devices need to take the heat dissipation into consideration, especially the electrical devices with heavy loads, such as the inverter. The existing electric equipment only considers the self heat dissipation requirement and does not consider the heat dissipation design matched with the whole environment. When the electrical equipment is installed in the cabinet, the cabinet also needs to be provided with a heat dissipation device for the electrical equipment, and most commonly, a heat dissipation fan is used. However, the current electrical equipment is not designed with a heat dissipation scheme which is coordinated with the cabinet, and usually, the cabinet itself is designed with an independent ventilation and heat dissipation system. However, in some cases, for example, in a car as a house exposed to sunlight, the temperature in the car may be very high, but the electrical equipment may be in a closed or no-load state, and heat dissipation is not required, and if the temperature control switch of the electrical cabinet starts the heat dissipation system, unnecessary energy consumption will be increased or decreased undoubtedly. If the temperature difference control method is adopted for control, unnecessary cost and power consumption are increased.
SUMMERY OF THE UTILITY MODEL
In order to let electrical equipment and regulator cubicle keep coordinating unanimously in the aspect of the heat dissipation, the utility model provides an electrical equipment of external heat dissipation switch in area to solve the prior art's that mentions in the background art weak point.
The technical scheme of the utility model as follows: the electric equipment with the external heat dissipation switch comprises the electric equipment, and the realization method is that one or more temperature sensing switches are arranged at the position of a high-temperature part of the electric equipment, the temperature sensing switches are normally open and are connected to an external interface, when the temperature of the high-temperature part rises to a set temperature, the temperature sensing switches are closed, a heat dissipation fan on the external electric cabinet is switched on, and heat dissipation is realized.
The utility model discloses can also adopt signal relay's mode to realize, connect a little signal relay on electrical equipment's temperature control circuit promptly, when the radiator fan during operation of this equipment, signal relay open end is closed normally simultaneously, and the radiator fan on the external regulator cubicle of switch-on realizes the heat dissipation.
The utility model has the advantages that:
the utility model provides a synchronous problem in the aspect of the heat dissipation between electrical equipment and the regulator cubicle, abandoned the regulator cubicle and adopted temperature control system to increase unnecessary cost and load alone. The heat dissipation control of the electrical cabinet is more accurate.

Detailed Description
The invention is explained in further detail below with reference to the drawings:
example 1: as shown in fig. 1: an inverter with an external radiating switch comprises an inverter 1, wherein a temperature sensing switch 3 is arranged on a heating center H bridge radiating fin 2 of the inverter, and the temperature sensing switch is connected with an external socket 4 on a shell; when the inverter is installed in an electric cabinet, a heat radiation fan 5 is arranged in the electric cabinet, the fan is powered by a power supply 6, and a negative electrode in a power supply circuit of the power supply 6 is connected with a temperature sensing switch 3 in the inverter through a plug-in connector 4 on a shell of the inverter. When the temperature of the H bridge of the inverter is lower than the design temperature of the temperature sensing switch, the temperature sensing switch is switched off, the external fan does not operate, and when the temperature of the H bridge exceeds the design temperature of the temperature sensing switch, the temperature sensing switch is switched on, and the external fan operates.
Example 2: as shown in fig. 2: an inverter with an external heat dissipation switch comprises an inverter 1, wherein a signal relay 7 is arranged in the inverter, a control pin of the signal relay is connected with a temperature control circuit of the inverter, and a switch pin of the signal relay is connected with a plug-in connector 4. When the inverter is installed in an electrical cabinet, the negative pole between a fan 5 and a power supply 6 in the electrical cabinet is controlled by a signal relay 7 through a connector 4. When the inverter fan works, the signal relay synchronously acts to switch on a fan circuit of the electrical cabinet, the fan works, and when the inverter fan stops working, the relay is disconnected to close the electrical cabinet fan.
Example 3: as shown in fig. 3: an inverter with an external heat dissipation switch comprises an inverter 1, wherein a main board 8 is arranged in the inverter, two wires are directly separated from a fan control circuit on the main board and connected to a plug connector 4 of a shell for controlling a fan 5 of an electrical cabinet. Thus, when the inverter fan runs, the fans of the electrical cabinets run synchronously.
Preferably, when the inverter fan works by using the voltage reduction circuit on the main board, the working capacity of the voltage reduction circuit needs to be considered, in order to ensure that the electrical cabinet fan has sufficient heat dissipation power, the negative electrode of the external fan uses the negative electrode of the control circuit, and the positive electrode of the external fan is directly connected with the positive electrode of the inverter input. By adopting the scheme, the use voltage of the heat radiation fan of the electric cabinet can be limited.
