Description
Technical field
The utility model relates to a kind of switch, be specifically related to a kind of outdoor intelligent demarcation switch.
Background technology
[0002] outdoor intelligent demarcation switch is a kind of outdoor high voltage switchgear; normally be made up of breaker body and controller and external voltage transformer three parts; three is connected by cable; there is fault detection capability; protecting control function and communication function; can reliably judge, sense switch into and out of the zero-sequence current of line side and phase fault electric current, realize excision earth fault and phase fault automatically.
Because measurement mechanism and switching device are separated type, in construction, the two is installed respectively, this increases not only workload and labour intensity, nor be beneficial to the unification of device is patrolled and examined and maintenance.Switching device needs workman's manual operations, therefore has specific requirement to the safe distance of high pressure, if metering device and switching device are integrated together, then metering device with high pressure can produce threat to the safety of human body.In order to avoid there are the problems referred to above, existingly occurring that metering device and switching device are assembled an entirety by a kind of control cabinet, effectively can eliminate high pressure and leaking outside to the threat of human body.But this integrated form control cabinet inlet wire side and outgoing line side close together, safe distance is comparatively short, requires high, improve product cost to graded dielectric material.
Prior art is that metering device and switching device are assembled an entirety, but this integrated form control cabinet inlet wire side and outgoing line side close together on market, and safe distance is comparatively short, requires high, improve product cost to graded dielectric material.Current transformer is fixed on high-pressure side, bears instrument transformer deadweight for a long time and conducting rod can be made to bend, make vacuum tube loose contact, easily cause equipment burnout.
Summary of the invention
For the deficiency that prior art exists, the utility model object is to provide a kind of outdoor intelligent demarcation switch, by three re-detections; the fault of electric power system can be judged more accurately; timely roof-cut resistence, and avoid misoperation, improve equipment protection precision.
To achieve these goals, the utility model realizes by the following technical solutions: a kind of outdoor intelligent demarcation switch, comprise end of incoming cables, leading-out terminal, casing, current transformer integrating device, voltage direction transducer and on-off control action device, casing is provided with end of incoming cables, leading-out terminal summation current transformer integrating device, box house is provided with voltage direction transducer and on-off control action device, end of incoming cables place is provided with fuse, end of incoming cables and current transformer integrating device are electrically connected, current transformer integrating device is fixed on the insulating case of casing and leading-out terminal by anchor leg pipe.
As preferably, described anchor leg pipe is more than Q20 copper bar.
As preferably, described current transformer integrating device inside is integrated with zero sequence current mutual inductor summation current transformer, and current transformer arranges terminals, and current transformer is also connected with leading-out terminal control switch.
The beneficial effects of the utility model: current transformer integrating device is arranged in the middle of inlet wire side and outgoing line side by the utility model, add the safe distance of both sides, reduce graded dielectric material.By anchor leg pipe fixed support, dramatically reduce the weight that current transformer is applied directly to conducting rod, avoid conducting rod to bend, add stability and fail safe.
Accompanying drawing explanation
The utility model is described in detail below in conjunction with the drawings and specific embodiments;
