Abstract
The utility model relates to a high-reliability electronic transformer which is mainly characterized in that the high-reliability electronic transformer comprises a sensor head, an electronic circuit module, a control module, a main power module and a standby power module, wherein the control module is connected with the main power module, the standby power module and the electronic circuit module and used for controlling the main power module and the standby power module to supply the electronic circuit module with power, and the electronic circuit module is connected with the sensor head to be used in secondary signal processing. The high-reliability electronic transformer has a reasonable design that the electronic circuit module, the control module, the main power module and the standby power module are relatively independent by utilization of a modularization design, thereby facilitating the equipment repair and maintenance; and the power module is separated from the electronic circuit module, and the rapid switching between a main/standby power is achieved by the control module, and therefore the reliability of the electronic transformer is largely improved.
Description
Technical field
The utility model belongs to the intelligent substation technical field, especially a kind of electronic mutual inductor of high reliability.
Background technology
Along with the development of electric system to high voltage, big capacity and digitizing direction, electronic mutual inductor is widely used in the intelligent substation.At present, one of electronic mutual inductor gordian technique is that power supply is supplied with problem, and the stability of power supply directly affects the reliability that electronic mutual inductor uses.Existing electronic mutual inductor just power supply is solidificated in the electronic circuit module, has the low problem of power supply reliability like this, and when power supply damages, change the monoblock electronic circuit board, all brings great inconvenience for repair and maintenance.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of reasonable in design, reliability is high and the repair and maintenance electronic mutual inductor of high reliability easily.
The utility model solves its technical matters and takes following technical scheme to realize:
A kind of electronic mutual inductor of high reliability, comprise sensor head, electronic circuit module, control module, main power source module and standby power supply module, control module is connected with main power source module, standby power supply and electronic circuit module respectively, being used for control main power source module and standby power supply module is the electronic circuit module power supply, and electronic circuit module is connected with sensor head and handles for secondary singal.
And described electronic circuit module, control module, main power source module and standby power supply module all adopt the board plug type module to be connected.
Advantage of the present utility model and good effect are:
The utility model is reasonable in design, and it adopts modular design to make to have relative independentability between electronic circuit module, control module, main power source module and four modules of standby power supply module, be convenient to maintenance and the maintenance of equipment; Simultaneously, power module is separated and realized the quick handoff functionality of main power supply by control module from electronic circuit module, improved the reliability of electronic mutual inductor greatly.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is further described:
A kind of electronic mutual inductor of high reliability, as shown in Figure 1, comprise sensor head, electronic circuit module, control module, main power source module and standby power supply module, main power source module is connected with control module with standby power supply, control module also is connected with electronic circuit module, control module realizes the handoff functionality of main power supply, control main power source module and standby power supply module are the electronic circuit module power supply, main power source module is used for electronic circuit is powered for a long time, standby power supply module is used for after the primary power dead electricity electronic circuit being powered, the power supply supply respect adopts dual power supply, after the primary power dead electricity, can pass through control module, restore electricity rapidly, improve the reliability that electronic mutual inductor uses greatly.Electronic circuit module is connected with sensor head, and electronic circuit is used for secondary singal to be handled.In the present embodiment, electronic circuit module, control module, main power source module and standby power supply module all adopt the board plug type module, when wherein operational blocks which partition system has problem, can carry out repair and maintenance easily, and not influence other modules.
It is emphasized that; embodiment described in the utility model is illustrative; rather than it is determinate; therefore the utility model is not limited to the embodiment described in the embodiment; every by those skilled in the art according to other embodiments that the technical solution of the utility model draws, belong to the scope of the utility model protection equally.
