Abstract
The utility model discloses a temperature control alarm device of a circuit breaker mechanism box. The temperature control alarm device comprises a temperature measuring element, wherein the temperature measuring element is connected with an external alternative-current power supply and a connection terminal in the circuit breaker mechanism box, and the connection terminal is connected with an external monitor by a connection cable; the temperature measuring element comprises a normally closed contact and a temperature sensor, the temperature sensor is connected to the normally closed contact; when the temperature is normal, the normally closed contact is opened, and when the temperature is not normal, the normally closed contact is closed, and the temperature signal sensed by the temperature sensor is transferred to the external monitor. The external alternative-current power supply is the power supply of the circuit breaker. The temperature control alarm device of the circuit breaker mechanism box in the embodiment of the utility model can timely detect the circuit breaker fault caused by heating devices in the circuit breaker mechanism box, therefore the safety operation of power grid is guaranteed.
Description
Technical field
The utility model relates to field of power, relates in particular to the detection field of the isolating switch in the electric system, is a kind of temp. controlling alarm of circuit breaker mechanism case concretely.
Background technology
At present, along with developing rapidly of electric system, each transformer station (institute) isolating switch (liquid, air pressure) mechanism case all adopts traditional temperature-adjusting heating device, purpose be prevent winter temperature cross low and affect isolating switch minute, closing operation.Because former design heating circuit disappears without heating power supply and the warning device of well heater damage, add present transformer station and mostly adopt unattended system, if make an inspection tour not in place, above-mentioned situation occurs and just be difficult to guarantee the normal running of isolating switch and the regular event under the malfunction, thereby make fault spread, affected the safe operation of electrical network.
The utility model content
The purpose of this utility model is to provide a kind of circuit breaker mechanism case temp. controlling alarm, can not in time find in the prior art owing to the circuit breaker failure that causes of heating reason in order to solve, thereby affect the problem of the safe operation of electrical network.
In order to achieve the above object, the utility model embodiment discloses a kind of circuit breaker mechanism case temp. controlling alarm, comprises a temperature element; Wherein, described temperature element connects the connection terminal in external ac power source and the described circuit breaker mechanism case, and described connection terminal connects the outer monitoring device by stube cable; Described temperature element comprises a normally closed contact and temperature sensor, and described temperature sensor connects described normally closed contact; When temperature was normal, described normally closed contact was opened, and when temperature was undesired, described normally closed contact was closed, with described temperature sensor senses to temperature signal send described outer monitoring device to.
Preferably, described external ac power source is the power supply of described isolating switch.
The circuit breaker mechanism case temp. controlling alarm of the utility model embodiment can in time be found the circuit breaker failure that causes owing to the heating arrangement reason in circuit breaker mechanism case, thereby provides safeguard for the safe operation of electrical network.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiment more of the present utility model, for those skilled in the art, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of the circuit breaker mechanism case temp. controlling alarm among the utility model embodiment;
Fig. 2 is the structural representation of the temperature element in the circuit breaker mechanism case temp. controlling alarm among the utility model embodiment;
Fig. 3 is the structural representation that a plurality of temp. controlling alarms of utilizing of the utility model embodiment detect a plurality of isolating switchs.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
Fig. 1 is the structural representation of the circuit breaker mechanism case temp. controlling alarm among the utility model embodiment.As shown in the figure, the circuit breaker mechanism case temp. controlling alarm among the utility model embodiment comprises a temperature element 2; Wherein, the connection terminal 3 that described temperature element 2 connects in external ac power source 1 and the described circuit breaker mechanism case, described connection terminal 3 connects outer monitoring device 5 by stube cable 4.
In the present embodiment, described external ac power source 1 can be the power supply of described isolating switch, and temperature element 2, connection terminal 3 and stube cable 4 all are positioned at described circuit breaker mechanism case.
Fig. 2 is the structural representation of the temperature element in the circuit breaker mechanism case temp. controlling alarm among the utility model embodiment.Described temperature element comprises a temperature sensor 201 and a normally closed contact 202, and when temperature was normal, described normally closed contact 202 was opened, and isolating switch normally moves; When temperature is undesired, described normally closed contact 202 closures, the temperature signal that described temperature sensor 201 is sensed sends described outer monitoring device 5 to.
In the present embodiment, when the temperature that senses described circuit breaker mechanism case when described temperature sensor 201 is lower than-5 ℃, normally closed contact 202 will be closed, thereby temperature signal is sent to outer monitoring device 5 by connection terminal 3 and stube cable 4, and temp. indicator is unusual in monitor, and the operator on duty is in time found and handling failure.Provide the mode of temperature anomaly to have a lot, for example can audible alarm be set according to temperature signal, when temperature signal is lower than-5 ℃, the sound playing system of monitor can send alarm bell sound, thereby inform operator on duty's abnormal conditions, certainly, also light warning etc. can be set, these belong to general knowledge known in this field, so do not give unnecessary details at this.
Fig. 3 is the structural representation that a plurality of temp. controlling alarms of utilizing of the utility model embodiment detect a plurality of isolating switchs.As shown in Figure 3, can in each circuit breaker mechanism case of a plurality of isolating switchs, a temp. controlling alarm be set, each temp. controlling alarm all sends alerting signal to watch-dog, and therefore break down and all can send alerting signal in any loop, guaranteed the safe and stable operation of electrical network.
The circuit breaker mechanism case temp. controlling alarm of the utility model embodiment can in time be found the circuit breaker failure that causes owing to the heating arrangement reason in circuit breaker mechanism case, thereby provides safeguard for the safe operation of electrical network.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above only is specific embodiment of the utility model; and be not used in and limit protection domain of the present utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
