Description

Remote signaling trigger assembly for circuit on-off feedback

Technical Field

The utility model belongs to the technical field of lightning protection electrical equipment, and particularly relates to a remote signaling trigger assembly for circuit on-off feedback.

Background

The remote signaling refers to the switching value of the remote communication data, such as the on/off state of a breaker or a disconnecting switch, the action/resetting of a protection signal, the input/output of an AGC/AVC function, and the like, and is usually represented by 1 or 2 binary bits. The remote signaling signal is required to adopt a passive contact mode, namely, the input of a certain path of remote signaling quantity is the contact of a pair of relays, and the contacts are closed or opened. And the YX module is used for converting the closing or opening of the relay contact into a low-level or high-level signal and sending the low-level or high-level signal to the RTU through the remote signaling terminal board. The running state signal of the automatic regulating device and other signals which can be output in a relay mode are provided; accident total signal and device main power supply power failure signal, etc.

The telemetry function is typically used to measure the position signal of the switch, the integrated fault signal of the transformer, the action signal of the protection device, the operating condition signal of the communication equipment, the tap position signal of the tap of the regulating transformer. The prior art is a simple mechanical feedback component applied to the on-off detection in some conventional switching devices or circuit protection devices, and does not have the function of electric signal communication feedback. Because these circuit protection devices adopt standard structural design, the circuit power-on detection in the circuit protection devices tends to set some more complex structures, which results in the influence of volume change on installation and use. The common mechanical feedback structure can only be checked on site, otherwise, whether the mechanical feedback structure is disconnected or not cannot be determined, but once the brake is disconnected or a degradation short circuit condition occurs, the state of the mechanical feedback structure is not obtained in time, so that a subsequent larger accident occurs. Therefore, the components with the remote signaling function are arranged in the circuit protection equipment, and signal feedback is carried out through external line connection, so that the circuit protection equipment is an effective monitoring means. The existing remote signaling components are various, have sensor detection types and mechanical linkage triggering types, generally aim at mechanical linkage triggering type structures, generally adopt components integrally formed with a tripping structure, and directly realize corresponding technical effects through cooperation of the tripping mechanism and a remote signaling switch. However, the tripping mechanism is limited to circuit breakers having a switch assembly, and other circuit protection devices without a switch assembly do not have a corresponding remote signaling trigger structure.

Disclosure of Invention

In order to solve the problems in the prior art, the utility model provides a remote signaling trigger assembly for circuit on-off feedback, which is different from the existing integrated remote signaling structural scheme, and is provided with a moving part alone, and is matched with an action piece to form a trigger relationship in a linkage way, and then forms a feedback circuit with a separately arranged remote signaling switch, so that the remote signaling trigger assembly can be used in other circuit protection devices except circuit breakers.

The technical scheme adopted by the utility model is as follows:

the utility model discloses a remote signaling trigger assembly for circuit on-off feedback, which is linked with an action piece for controlling circuit on-off, and comprises a fixed remote signaling switch and a moving part which moves relative to the remote signaling switch, wherein the moving part is provided with a first end part which is in linkage fit with the action piece and keeps insulated and isolated, and a second end part which is matched with the remote signaling switch, the action piece acts to cause the first end part of the moving part to bear force, and the forced action of the moving part causes the second end part to trigger the remote signaling switch;

Or insulating materials are arranged at the contact parts for isolation, so that corresponding effects can be achieved.

The linkage refers to a relative action linkage relation between structures, and does not necessarily keep contact, but can realize a transmission effect in an indirect contact or non-contact mode through a magnetic piece or other modes, and the linkage is defined as that when the driving structure acts, the driven structure acts simultaneously or in a delayed mode, and corresponding control and feedback are realized through the action of the driven structure.
