Abstract
The invention relates to a temperature monitoring device which is particularly suitable for a high-frequency switching power supply. Currently, as the problem of heat-dissipation system failures of a high-frequency switching power supply of a direct-current system is not taken into account, the damage arising from ultra-high temperature sometimes occur, and the heat-dissipation system failures are fan power failures in the majority. The invention discloses a temperature monitoring device for a high-frequency switching power supply, wherein the temperature monitoring device consists of a temperature relay, an intermediate relay and a signal module. The temperature relay is arranged in a high-frequency switching power supply cabinet, and a coil of the intermediate relay is in series connection with a fan power supply circuit of a heat-dissipation system of the high-frequency switching power supply. With the adoption of the temperature monitoring device for the high-frequency switching power supply, the problem of damage to the high-frequency switching power supply arising from ultra-high temperature is solved by using low cost, the fan power failures can be prompted, and thus, the maintenance workload is alleviated.
Description
Technical field
The present invention relates to a kind of device for monitoring temperature, be specially adapted to the high frequency switch power cabinet.
Background technology
The straight-flow system high frequency switch power is widespread usage in the electric system; The processing mode of high frequency switch power cooling system generally is to install fan additional to carry out temperature control air-cooled; Owing to do not consider the problem after its cooling system fault, when summer operation, superhigh temperature takes place sometimes damage; Mostly be that the high frequency switch power air cooling system damages and to cause the too high and scaling loss of power supply internal temperature, and in the majority with the fan power supply fault in the cooling system fault.
Summary of the invention
The object of the invention addresses the above problem for low cost exactly, and a kind of high frequency switch power device for monitoring temperature is provided.
Technical scheme of the present invention is a kind of high frequency switch power device for monitoring temperature, it is characterized in that: the normally opened contact of temperature relay links to each other with signaling module respectively with the normally closed contact of auxiliary reclay.Temperature relay is placed in the high frequency switch power cabinet, and the coil tandem of auxiliary reclay is in the fan power supply loop of high frequency switch power cooling system.Signaling module can adopt the mode that inserts in the conventional central signal system of transformer station during of the present invention enforcement, can be used as the mode in the switching value input transformer station complex control system again.
The invention has the beneficial effects as follows: with very low cost, solve the problem that high frequency switch power generation superhigh temperature is damaged, can remind the fan power supply fault again, alleviate maintenance load.
Description of drawings
Fig. 1 is principle cabinet figure of the present invention.
Fig. 2 is the circuit diagram of the embodiment of the invention.
In the accompanying drawing, the 1. normally opened contact of temperature relay, 2. normally closed contact, 3. coil, 4. fan power supply loop, 5. temperature relay, 6. auxiliary reclay, 7, the signaling module of center-off device of auxiliary reclay.
Embodiment
With reference to accompanying drawing, embodiment of the present invention is for when high frequency switch power cabinet internal temperature surpasses setting value, the temperature relay action, and the normally opened contact closure of temperature relay is sent the high frequency switch power cabinet internal temperature signal that exceeds standard through signaling module; After the staff handled, temperature relay recovered, and the normally opened contact of temperature relay breaks off, the high frequency switch power cabinet internal temperature blackout that exceeds standard.When the fan power supply loop fault of high frequency switch power cooling system takes place when, make the coil losing electricity of center-off device, the normally closed contact of center-off device is closed, sends high frequency switch power cabinet fan power supply loop fault signal through signaling module; After the staff handled, the fan power supply loop fault was eliminated, and makes the coil conducting of center-off device, and the normally closed contact of center-off device breaks off, high frequency switch power cabinet fan power supply loop fault blackout.
When environment temperature is higher, if temperature exceeding standard signal and fan power supply fault-signal occur simultaneously, reminds then that the staff is the temperature exceeding standard that the fan power supply fault causes, otherwise be other partial fault of cooling system.When environment temperature is low, the fan power supply fault occurs and in time remind the staff to keep in repair.
During enforcement of the present invention, signaling module can adopt the mode that inserts in the conventional central signal system of transformer station, through the flashing light and the alarm bell prompting substation operation personnel of central signal system; Can be used as the mode in the switching value input transformer station complex control system again, through the monitor staff in computer interface and sound prompting substation operation personnel or a distant place.
Except that the foregoing description, the present invention can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation form, all drop on the protection domain of requirement of the present invention.
