Abstract
The utility model relates to a distribution transformer theft-judge sensor which belongs to the distribution transformer anti-theft device technique field. The sensor includes an alarm emitting device, also includes a mercury switch which is installed on the distribution transformer body, the output is series connected in a switch circuit of the alarm emitting device through a connecting cable. Thus, the distribution transformer is lift that will cause the mercury switch being shock or inclined, accordingly, the switch circuit is closed and the alarm emitting device is touched for emitting an alarm signal, accordingly, mis-alarm caused by the distribution transformer self circuit fault or normal inspection are avoided.
Description
Technical field
The utility model relates to a kind of sensor, and discriminating sensor is stolen in especially a kind of distribution transforming, belongs to substation transformer anti-thefting facility technical field.
Background technology
Understand according to the applicant, existing distribution transforming burglar alarm mainly relies on to install on the substation transformer and utilizes solar powered alarm transmission device.This alarm transmission device can send warning when the substation transformer dead electricity, and by wireless transmission, makes the related personnel in time obtain feedback information, thereby rush towards the relevant matters of site disposal.
Facts have proved; whether this existing warning device has electricity as the fault or forced outage, the normal maintenance etc. that judge whether that stolen foundation can not active zone be divided substation transformer self by gathering substation transformer merely; usually can cause false alarm, cause unnecessary interlock reaction.
The utility model content
The purpose of this utility model is: at the shortcoming that above-mentioned prior art exists, propose a kind of distribution transforming that can avoid reporting by mistake and steal discriminating sensor.
In order to reach above purpose, distribution transforming of the present utility model is stolen discriminating sensor and is comprised the alarm transmission device, also comprise mercury cut-off, described mercury cut-off is placed on the transformer body, and its output is connected in the on-off circuit of alarm transmission device by stube cable.
Like this, when substation transformer is lifted, will cause mercury cut-off to be given a shock or tilt, thereby Closing Switch circuit, trigger the alarm transmission device, send alerting signal, thus the wrong report of avoiding factors such as substation transformer self fault or normal maintenance to cause.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the principle of work block diagram of an embodiment of the utility model.
Fig. 2 is the structural representation of an embodiment of the utility model.
Embodiment
Embodiment one
The distribution transforming of present embodiment is stolen discriminating sensor as described in Figure 2, trigger-type alarm transmission device 2 is fixed on the pillar of substation transformer, mercury cut-off 3 positioned vertical are in the inside of transformer body 4, its output passes the loam cake hole 5 of transformer body, is connected on by stube cable 1 in the on-off circuit of trigger-type alarm transmission device 2.
Embodiment two
The distribution transforming of present embodiment steal discriminating sensor and embodiment one different be mercury cut-off 3 horizontal settings covering greatly at transformer body 4.
Like this, when the substation transformer loam cake is lifted or during whole being overthrown, to cause mercury cut-off to experience sharp pounding or run-off the straight, thereby Closing Switch circuit, trigger the comparison loop in the alarm transmission device, short circuit D, open circuit K are judged, in time send alerting signal after confirming to belong to improper situation, avoid substation transformer stolen (referring to Fig. 1).
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
Claims (4)
1. discriminating sensor is stolen in a distribution transforming, comprises the alarm transmission device, and it is characterized in that: also comprise mercury cut-off, described mercury cut-off is placed on the transformer body, and its output is connected in the on-off circuit of alarm transmission device by stube cable.
2. discriminating sensor is stolen in distribution transforming according to claim 1, and it is characterized in that: described mercury cut-off positioned vertical is in the transformer body interior.
