Abstract
The utility model relates to an intelligent medium voltage switch cabinet, and aims to provide the intelligent medium voltage switch cabinet which is accurate in temperature detection and simple in structure. The technical scheme of the utility model is that the intelligent medium voltage switch cabinet comprises a vertically-arranged cabinet body which is provided with a bus chamber, a breaker chamber and a cable chamber; a breaker handcart is disposed in the breaker chamber; the bus chamber is provided with three wiring terminals and three breaker contact boxes, wherein the wiring terminals are communicated with a power supply bus, and the breaker contact boxes are mated with the contact of the breaker handcart; each wiring terminal is connected with one breaker contact box via a bus bar; and three temperature sensors for detecting the temperature of each bus bar are arranged on the cabinet wall of the bus chamber. The intelligent medium voltage switch cabinet is characterized in that the panels of connecting ends between the three bus bars and the breaker contact boxes are arranged along a vertical direction, and the panels are perpendicular to the axis of each temperature sensor. The vertical distance between the bending point of each bus bar and the topmost edge of each breaker contact box is 4 to 6cm.
Description
Technical field
The utility model relates to a kind of power equipment, is specifically related to a kind of intelligent Medium Voltage Switchgear.
Background technology
In the bus-bar room of intelligent Medium Voltage Switchgear, for temperature, the temperature rise situation of monitoring breaker dynamic/static contact junction, the on-line monitoring temperature sensor of common meeting equipped with non-contact in cabinet wall nearer above contact box.For obtaining temperature signal comparatively accurately and reliably, require the plate face of tested busbar to become 90 degree with the axis angle of temperature sensor, distance is no more than 150mm, and the signal source that detects of temperature transducer is circle like this, and error is less.
In the bus-bar room of traditional Medium Voltage Switchgear, traditional busbar mounting means is to lean on contact box edge to begin flanging, connects with the binding post of each mutually horizontal main bus bar again.Will cause wherein two busbars and temperature transducer can't form the thermometric angle of 90 degree like this, temperature signal (infrared ray) is relatively dispersed, and is difficult to obtain temperature measurement result accurately.
Summary of the invention
The purpose of the utility model is the deficiency that overcomes in the above-mentioned background technology, and a kind of intelligent Medium Voltage Switchgear is provided, and it is accurate that this intelligence Medium Voltage Switchgear should have temperature detection, characteristic of simple structure.
For realizing above purpose, the technical scheme below the utility model has adopted:
A kind of intelligent Medium Voltage Switchgear comprises the cabinet of a vertical layout being shaped on bus-bar room, breaker chamber and cable vault in this cabinet; Be provided with circuit breaker cart in the said breaker chamber; Be provided with the contact of breaker box that the contact of three binding posts of connecting with power source bus, three and circuit breaker cart is complementary in the said bus-bar room; Each binding post is connected with a contact of breaker box through a busbar respectively; Also be equipped with three in the cabinet wall of bus-bar room and be respectively applied for the temperature sensor that detects each busbar temperature; It is characterized in that: the plate face of the link of said three busbars and contact of breaker box all vertically arranges, and all with the axis normal of temperature sensor.
The vertical range of the upper edge of the inflection point of said three busbars and contact of breaker box is 4-6cm.
The beneficial effect of the utility model is: three busbars are all from beginning bending apart from the upper edge 4-6cm of contact of breaker box; Make the plate face of three busbars all can face a temperature sensor; Promptly become 90 degree angles with the axis of temperature sensor; Temperature signal (infrared ray) is more concentrated, and the temperature measurement result that obtains is more accurate.

Embodiment
Below in conjunction with Figure of description, the utility model is described further, but the utility model is not limited to following examples.
As shown in Figure 1, the described a kind of intelligent Medium Voltage Switchgear of the utility model comprises the cabinet 8 of a vertical layout, and this switch cubicle body interior is shaped on bus-bar room 2, breaker chamber 1 and cable vault 3.It is (as shown in Figure 4 that three busbars are installed in the said bus-bar room; The first busbar A1, the second busbar A2, the 3rd busbar A3); One end of every busbar connects a binding post 4 (binding post is connected with power source bus); The other end connects a contact of breaker box 5, also is equipped with three in the cabinet wall of bus-bar room and is respectively applied for the temperature sensor that detects each busbar temperature.Accordingly, three contact of breaker boxes are installed also in the said cable vault, working cable is connected on this contact of breaker box.Said breaker chamber is used to install circuit breaker cart 7 (being shaped on the guide rail of handcart motion in the breaker chamber); Three contacts on circuit breaker cart upper strata insert contact of breaker box corresponding in the bus-bar room respectively, and three contacts of lower floor insert contact of breaker box corresponding in the cable vault respectively to connect working cable and power source bus.Be provided with earthed switch in the cable vault.Said structure of the utility model and ordinary tap cabinet are similar, and its operation principle is not described in detail.
In order to make temperature sensor can detect temperature, the temperature rise data of busbar exactly, the utility model is made following improvement.
As shown in Figure 4; In the utility model; The plate face of the link of said three busbars and contact of breaker box is all vertically arranged; And all with the axis normal of temperature sensor 6, the vertical range of the upper edge of the inflection point of said three busbars (among Fig. 4 shown in the C point) and contact of breaker box (among Fig. 4 shown in the D point) is 4-6cm (specifically definite according to actual conditions), and the horizontal range of temperature sensor and bus plate face is no more than 150mm.Be the plate face that temperature sensor faces busbar, the plate face of busbar becomes 90 degree angles with the axis of temperature sensor, and temperature signal (being generally infrared signal, shown in arrow among Fig. 2, Fig. 4) is more concentrated, and the temperature measurement result that obtains is more accurate.
