Abstract
本发明涉及一种温度监控装置，特别适用于高频开关电源。目前由于直流系统高频开关电源没有考虑到其散热系统故障的问题，有时会发生超高温损坏，而散热系统故障中又以风扇电源故障居多。本发明公开一种高频开关电源温度监控装置，由温度继电器、中间继电器和信号模块组成。温度继电器安放在高频开关电源柜内，中间继电器的线圈串接在高频开关电源散热系统的风扇电源回路中。本发明以很低的成本，解决高频开关电源发生超高温损坏的问题，又能提醒风扇电源故障，减轻维修工作量。
The invention relates to a temperature monitoring device, which is especially suitable for high-frequency switching power supply. At present, because the high-frequency switching power supply of the DC system does not consider the problem of the failure of its cooling system, sometimes ultra-high temperature damage occurs, and the failure of the fan power supply is the majority of the failures of the cooling system. The invention discloses a high-frequency switching power supply temperature monitoring device, which is composed of a temperature relay, an intermediate relay and a signal module. The temperature relay is placed in the high-frequency switching power supply cabinet, and the coil of the intermediate relay is connected in series in the fan power circuit of the cooling system of the high-frequency switching power supply. The invention solves the problem of ultra-high temperature damage to the high-frequency switching power supply at a very low cost, and can remind the fan power supply of failure, reducing the maintenance workload.
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.
