Abstract

It the utility model is related to dismountable parallel resistance structure between a kind of twin conductor, the parallel resistance structure includes the H-shaped plastic cement frame of a symmetrical configuration, it is fixedly mounted with built-in copper core intubation respectively in two parallel edges bottoms of H-shaped plastic cement frame, copper core intubation lower ending opening top is connected with built-in core, after built-in core is passed by H-shaped plastic cement frame top, core covering is enclosed with its underpart periphery, it is exposed at the top of built-in core, simultaneously, built-in measuring resistance is fixed with the crossbeam in the middle part of H-shaped plastic cement frame, the both ends of measuring resistance are connected with the built-in core of the parallel edges of H-shaped plastic cement frame two.The utility model is when needing to use parallel resistance, plug the parallel resistance structure in that end that power plant's signal source need to be only connected in wire, you can obtain the wire with parallel resistance, greatly save test period and experiment difficulty, labor intensity is reduced, improves efficiency.

Description

Dismountable parallel resistance structure between a kind of twin conductor
Technical field
The utility model belongs to measuring instrument technical field, more particularly, to dismountable electricity in parallel between a kind of twin conductor Hinder structure.
Background technology
When carrying out every experiment to power plant, often use multiple conducting wires and be connected to signal between power plant electronics On source and tester, such as:Unit porthole shut-in time testing experiment, governing system modeling parameters testing experiment etc..Generate electricity The signal that factory provides is generally divided into two kinds of voltage signal and current signal, and due to the limitation of measuring instrument, some measuring instruments are only Can measurement voltage signal, and when measuring current signal if desired, that end parallel connection one of power plant's signal source can only be connected in wire Individual resistance, it is connected in power plant's signal source and is tested again afterwards.Under normal circumstances, due to the uncertainty of power plant's signal type, Need to carry out immediately at the scene in one end parallel resistance of wire, waste very much test period, and there is electricity in parallel making During the wire of resistance, the possibility of poor wire connection is added, causes signal not transmit, significant figure can not be obtained According to.
The content of the invention
The purpose of this utility model is overcome the deficiencies in the prior art, there is provided dismountable in parallel between a kind of twin conductor Electric resistance structure.
The utility model solves its technical problem and takes following technical scheme to realize:
Dismountable parallel resistance structure between a kind of twin conductor, twin conductor include connection instrument side, lead body and The terminals core of oversheath and internal layer core integument is peelled off, the parallel resistance structure includes the H-shaped modeling of a symmetrical configuration Glue frame, in two parallel edges bottoms of H-shaped plastic cement frame, built-in copper core intubation is fixedly mounted with respectively, copper core is intubated lower end Opening, top is connected with the built-in core being wrapped in H-shaped plastic cement frame, after built-in core is passed by H-shaped plastic cement frame top, at it Lower periphery is enclosed with core covering, and built-in core top is exposed, for the connection with test equipment, meanwhile, in H-shaped plastic cement frame Built-in measuring resistance is fixed with the crossbeam in portion, the both ends of measuring resistance connect with the built-in core of the parallel edges of H-shaped plastic cement frame two Connect.
Moreover, the length of the copper core intubation is between 10mm-15mm.
The advantages of the utility model and good effect are:
Dismountable parallel resistance structure between a kind of twin conductor of the present utility model, when needing to use parallel resistance, Plug the parallel resistance structure in that end that power plant's signal source need to be only connected in wire, you can the wire with parallel resistance is obtained, Test period and experiment difficulty are greatlyd save, labor intensity is reduced, improves efficiency, improve benefit.
Brief description of the drawings
Fig. 1 is twin conductor structure;
Fig. 2 is H-shaped plastic cement frame structural representation of the present utility model;
Fig. 3 is structural representation when the utility model uses.
Embodiment
The utility model embodiment is further described below in conjunction with accompanying drawing, it is emphasized that, implementation below It is illustrative, rather than limited, it is impossible to be used as in this embodiment to restriction of the present utility model.
Dismountable parallel resistance structure between a kind of twin conductor, as shown in figure 1, twin conductor includes connection instrument side 1, Lead body 2 and the terminals core 3 for peelling off oversheath and internal layer core integument, innovative point of the present utility model is, such as Fig. 2 Shown, the parallel resistance structure includes the H-shaped plastic cement frame 5 of a symmetrical configuration, in two parallel edges bottoms of H-shaped plastic cement frame, Built-in copper core intubation 8 is fixedly mounted with respectively, and copper core is intubated lower ending opening, and top is interior in H-shaped plastic cement frame with being wrapped in Put core 6 to connect, after built-in core is passed by H-shaped plastic cement frame top, core integument 4, built-in line are enclosed with its underpart periphery It is exposed at the top of core, for the connection with test equipment, meanwhile, built-in standard is fixed with the crossbeam in the middle part of H-shaped plastic cement frame Resistance 7, the both ends of measuring resistance are connected with core built in two parallel edges of H-shaped plastic cement frame.
In specific implementation of the present utility model, in order to ensure that the terminals core of twin conductor inserts copper core intubation Contact is good afterwards, and the length of the copper core intubation is between 10mm-15mm.
Use principle
The parallel resistance element when measurement signal is current signal, it is necessary between twin conductor, will be double in the way of Fig. 1 The terminals core of stock wire is stripped out, and two piece-root grafting line end cores are inserted in the copper core intubation of H-shaped plastic cement frame lower end respectively, As shown in figure 3, fixed after being plugged by insulating tape, the built-in core connecting test that now i.e. available H-shaped plastic cement frame top passes Equipment.
