Description

Distribution network test equipment of quick installation

Technical Field

The invention relates to power monitoring equipment, in particular to rapidly-installed power distribution network testing equipment.

Background

On-line detection techniques have been developed to address the issue of real-time measurement and control of such variables. The online detection technology is based on an inference estimator in inference control, namely, collecting some variables (also called secondary variables or auxiliary variables) which are easy to measure, and constructing a mathematical model taking the variables which are easy to measure as inputs to estimate main variables (also called main variables) which are difficult to measure. Therefore, support is provided for process control, quality control, process management, decision and the like, and a foundation is laid for further realizing quality control and process optimization.

The existing online cable detection equipment is generally covered on the surface of a cable, but the cable emits a large amount of heat during working, and the surface is covered with a layer of detection equipment, so that the temperature of the cable is too high, the conductivity is reduced, and the service life is shortened.

Disclosure of Invention

The invention aims to solve the technical problems that the conventional cable online detection equipment generally covers the surface of a cable, but the cable generates a large amount of heat during working, and the cable is easily overhigh in temperature, low in conductivity and short in service life because the surface is covered with a layer of detection equipment.

The invention is realized by the following technical scheme:

distribution network test equipment of quick installation, including at least two fixed knot that match with the cable construct, still include the arc fixed plate that matches with fixed knot constructs and the connecting plate that is used for connecting each arc fixed plate, the cross-section of connecting plate is the same with the arc fixed plate, still be provided with the connection structure who matches with the sensor on the fixed knot constructs, be provided with the data connector who matches with the sensor on the arc fixed plate and with the jack that the connecting plate matches, the connecting plate still is provided with the plug that matches with the jack.

This scheme is fixed on the cable through the mode that will change into at cable surface covering check out test set with check out test set's sensor probe through fixed knot structure, simultaneously, realizes the transmission of test data through a connecting plate of being connected with all fixed knot constructs, because the area of contact of fixed knot structure and cable is minimum, does not influence the heat dissipation of cable hardly, and effectual solution leads to the cable high temperature easily at surface covering one deck check out test set, and electric conductive property descends, the problem that life shortens. Meanwhile, a split type connecting plate structure is adopted, the number of the connecting plates and the number of the fixing structures can be determined according to requirements, and different measurement requirements can be met.

And the data line is connected with one of the arc-shaped fixing plate and the connecting plate. The sensor is convenient to transmit data to the outside through the data line.

The fixing structure is a clamping ring, the clamping ring is composed of an upper clamping ring and a lower clamping ring which are both semicircular arc-shaped plates, the upper clamping ring arc-shaped fixing plate is connected, and the groove is formed in the inner side wall of the lower clamping ring. Because it is fixed with the cable to go up the snap ring, consequently, be favorable to changing the sensor when needs with the sensor setting on the snap ring down, only need during the change pull down one snap ring can and need not pull down whole equipment.

One interface between the upper clamping ring and the lower clamping ring is hinged, and the other interface is connected by a buckle. Through articulating one end and the other end passes through the buckle and connects, reduced the quantity of solitary part, the part of avoiding lose and reduced maintainer's the operation degree of difficulty.

The fixing structure is a binding band, and the binding band is matched with the cable through combination of a joint arranged at one end of the binding band and other parts on the binding band.

The bandage is made of elastic materials. The length of the regulation bandage that can be more extensive, when installing on the cable simultaneously, increase the bandage to the pressure of cable, increase the friction between cable and the bandage, difficult not hard up.

Compared with the prior art, the invention has the following advantages and beneficial effects:

1. the invention relates to a power distribution network test device which is quickly installed;

2. the invention relates to a power distribution network testing device capable of being quickly installed.
