Abstract
The utility model relates to a novel voltage tripping signal source injecting terminal, which is mainly characterized in that a service wire and a load connection position are connected with short jacks which are arranged on respective conductor bodies in a short circuit via a short circuiting plunger, and injected signal jacks are arranged beside the short jacks of a load end. The utility model can be formed by a single-phase structure, and also be formed by the arrangement of a plurality of single phase structures. When the utility model is used for detection, the short circuiting plunger is unplugged, and detection signals are injected. The utility model has the advantages that detection operation is convenient and safe, and work efficiency is increased.
Description
The utility model relates to a kind of binding post of electrical field, relates in particular to a kind of novel voltage trip signal source and injects terminal.
In automation system for the power network dispatching factory station end telecontrol equipment, extensively adopt electric parameters transducer to gather electric parameters such as each electric substation's circuit is meritorious, idle, electric current, voltage, in order to guarantee the accuracy of image data, must carry out periodic check to transmitter according to rules.All adopt field-checking at present, as when carrying out the voltage field-checking, need the secondary circuit of voltage transformer is isolated from the transmitter input port, the isolation of voltage quite bothers, each phase voltage lead-in wire of introducing transmitter on the circuit from terminal or directly to be removed and carries out insulation measures in case short circuit from transmitter respectively, also need recover after work for inspection finishes, the screw that there is fixing cord at the two ends that existing terminal is actually conductor only plays the effect that connects lead.
The purpose of this utility model provides a kind of novel voltage trip signal source simple in structure, easy to operate, favourable detection and injects terminal.
The purpose of this utility model is achieved through the following technical solutions: terminal is injected in a kind of novel voltage trip signal source, the conductor that comprises conductor, load wiring place and the connection thereof of lead-in conductor wiring place and connection thereof, be open circuit between the conductor that it is characterized in that connecting lead-in wiring place and the conductor that is connected the load wiring place, each is provided with and is connected with the short circuit jack on two conductors of open circuit, short circuit jack on the load end conductor is other and have signal to inject jack, short circuit jack, signal inject jack and are fixed on the insulation shell, and corresponding short circuit jack is provided with short-circuiting plug.
The utility model utilizes short-circuiting plug to connect lead-in and load, when needing to detect, taking out short-circuiting plug makes between lead-in and the load and becomes open circuit, and inject jack by the signal that is arranged on short circuit jack one side on the load end conductor and insert detection signal, implement testing, the utility model is simple in structure, can phase structure, heterogeneous structure that also can several single-phase arrangements, detecting operation is convenient and safe, has improved operating efficiency.
Accompanying drawing 1 is one of a utility model structure schematic diagram;
Accompanying drawing 2 is two schematic diagrames of the utility model structure;
Accompanying drawing 3 is the three-circuit connection layout of the utility model structure;
In the accompanying drawing: the 1st, insulation shell, the 2nd, lead-in wiring place, the 3rd, lead-in wiring place conductor, the 4th, the short circuit jack, the 5th, inject the signal jack, the 6th, short-circuiting plug, the 7th, load wiring place, the 8th, load wiring place conductor.
Further specify the utility model in conjunction with the accompanying drawings and embodiments, the utility model is by the short circuit jack 4 that connects on the short circuit jack 4, load wiring place 7 and the conductor 8 that connects thereof that connect on insulation shell 1, lead-in wiring place 2 and the conductor 3 that connects thereof, the conductor 3, the conductor 8 and inject signal jack 5 and short-circuiting plug 6 constitutes, when short-circuiting plug 6 inserts two short circuit jacks 4, lead-in and load are connected, when needing to detect, take out short-circuiting plug 6.Make and form open circuit between lead-in and the load, detection signal is by injecting 5 inputs of signal jack and detecting, and short circuit jack 4, injection signal jack 5 are fixed on the insulation shell 1.
