Abstract
The utility model discloses a current and voltage detection type insulation sleeve of a ring net switch device, which belongs to the technical field of ring net distribution switch devices in an electric power system. The current and voltage detection type insulation sleeve of the ring net switch device comprises a conductive rod, a voltage sensor and a current sensor, wherein the conductive rod, the voltage sensor and the current sensor are in an integrated structure which is formed by epoxy resin pouring. According to the utility model, the current sensor, the voltage sensor and the insulation sleeve are organically combined together; the current and voltage detection type insulation sleeve has the performances of voltage and current detection, compact structure and small volume; and a signal detected by the current sensor and the voltage sensor is a weak current signal, which is convenient for digital conversion and the communication need based on an IEC61850 technology.
Description
Technical field
The utility model belongs to looped network distribution switchgear technical field in the electric system, is specially a kind of electric current, voltage detecting type insulating sleeve of looped network switch apparatus.
Background technology
In urban power distribution network, because underground cable line has advantages such as safe, reliable, attractive in appearance, make increasing distribution system adopt underground cable line, the distribution switchgear that underground cable line is commonly used is ring main unit and cable branch box.The electric current of these two kinds of switchgears, the voltage detecting way is that traditional electromagnetic current transducer and voltage transformer (VT) are installed in equipment box, ring main unit and cable branch box have not only been increased, also with the electromagnetism of electromagnetic current transducer and voltage transformer (VT) saturated, defectives such as electromagnetic resonance, on the other hand, development along with intelligent grid, based on the IEC61850 technology, current transformer and voltage transformer (VT) adopt electronic type or photo-electric mutual inductor, so that the digital conversion of signal, therefore, the switchgear that requires to install in ring main unit and the cable branch box has current sensor and voltage sensor, and at present, also do not have Related product in ring main unit and cable branch box, to use.
Summary of the invention
The purpose of this utility model is for a kind of electric current, voltage detecting type insulating sleeve of looped network switch apparatus are provided in the underground cable power distribution network of city, it is installed on the switchgear in ring main unit and the cable branch box, solve the technological deficiency that existing looped network switch apparatus exists by this invention, and the applied defect of existing looped network switch apparatus in intelligent grid.
The technical scheme that realizes above-mentioned purpose is: the electric current of looped network switch apparatus, voltage detecting type insulating sleeve, it is characterized in that: comprise conducting rod, voltage sensor and current sensor, described said elements is the integral structure that adopts poured with epoxy resin to form.
Described current transformer is capacitive divided voltage sensor.
Described voltage transformer (VT) is the Luo-coil sensor, and the Luo-coil sensor comprises insulcrete, and the tow sides of insulcrete evenly connect up respectively and are concatenated into a Luo-coil sensor.
The beneficial effects of the utility model are: current sensor, voltage sensor and insulating sleeve are organically combined, not only have voltage, current detecting performance, also have compact conformation, the little performance of volume; Signal by current sensor, voltage sensor senses is weak electric signal on the other hand, is convenient to digital conversion and the needs of communicating by letter based on the IEC61850 technology.
