Abstract
The present invention relates to a grounding transformer low-voltage side live display. The display comprises three voltage transformers, a three-phase live display and a wire with insulated skin. The three voltage transformers are respectively installed at each phase low-voltage cable at the low-voltage side of the transformer station grounding transformer; the three voltage transformers are connected with the input end of the three-phase live display through the wire with insulated skin; and the three-phase live display is installed at an observable position and is reliably connected with a ground wire. The grounding transformer low-voltage side live display is reasonable in design and is able to visually display whether the low-voltage side of the grounding transformer is electrified or not, and is able to effectively ensure the operator's safety and avoid the occurrence of accidents when a main transformer is required to power out and perform maintenance; and moreover, the grounding transformer low-voltage side live display is simple in structure, safe and reliable and easy to install, and is widely applicable to the field of maintenance of a transformer station.
Description
Technical field
The invention belongs to substation grounding transformer technology field, especially a kind of ground connection low pressure side electrification display.
Background technology
At present, many transformer stations adopt two to become four bus modes and run, and adopt in low resistance grounding situation at each Substation Station, and grounding transformer is installed directly in main transformer 10kV side, when main transformer needs interruption maintenance, stops grounding transformer load.In the process, if misoperation can cause grounding transformer to the anti-power transmission of transformator, existing grounding transformer low voltage side cable joint does not show the device with dotted state, and electrified voltage is generally low-voltage, and electroscope electric pressure is minimum for 10kV in existing station, it is impossible to whether detection grounding transformer is with voltage, in this case, security incident very easily occurs, jeopardizes the Radix Ginseng safety of operator.
Summary of the invention
It is an object of the invention to make up the deficiencies in the prior art part, it is provided that a kind of reasonable in design, ground connection low pressure side electrification display that safety is high and easy to use.
It is an object of the invention to be realized by techniques below means:
A kind of ground connection low pressure side electrification display, including three voltage transformers, a three-phase electrification display and tape insulation skin wire, described three voltage transformers are separately mounted on every phase low-voltage cable of substation grounding step down side, described three voltage transformers are connected with the input of three-phase electrification display respectively through tape insulation skin wire, described three-phase electrification display is arranged on Observable position, and this three-phase electrification display and ground wire are reliably connected.
Advantages of the present invention and having the benefit effect that
Three voltage transformers are arranged on grounding transformer low-voltage cable and electrification display are arranged on Observable position by the present invention, whether charged grounding transformer low voltage side cable can be demonstrated intuitively, when main transformer needs interruption maintenance, can effectively ensure the safety of operator, it is to avoid the generation of security incident.Meanwhile, the present invention have simple in construction, safe and reliable, the feature such as be easily installed, can extensive use and station field.
Accompanying drawing explanation
Fig. 1 is the circuit theory diagrams of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the embodiment of the present invention is further described:
A kind of ground connection low pressure side electrification display, as shown in Figure 1, including three voltage transformers, a three-phase electrification display and tape insulation skin wire, three voltage transformers are separately mounted on every phase low-voltage cable of substation grounding step down side, three-phase electrification display is arranged on Observable position, three voltage transformers are connected with the input of three-phase electrification display respectively through tape insulation skin wire, and three-phase electrification display and ground wire are reliably connected.
The operation principle of the present invention is:
Three voltage transformers detect the information of voltage on grounding transformer low-voltage cable in real time, and testing result is sent to three-phase electrification display, the voltage on every phase low-voltage cable can be demonstrated in real time by three-phase electrification display, when the voltage detected exceedes preset value, send sound and light alarm, thus effectively ensureing the safety of operator.
It is emphasized that; embodiment of the present invention is illustrative; rather than it is determinate; therefore the present invention includes the embodiment that is not limited to described in detailed description of the invention; every other embodiments drawn according to technical scheme by those skilled in the art, also belong to the scope of protection of the invention.
