Abstract
The utility model relates to the detection field of power system, in particular to a zero-power-outage test residual current operated intelligent protector. The zero-power-outage test residual current operated intelligent protector comprises a zero-sequence mutual inductor, a control unit, an operated relay and a release, wherein the release is matched with a disconnecting link connected with an incoming line interface, a testing reset switch is arranged between the release and the operated relay, two ends of the operated relay are connected with a test relay in parallel, the test relay is connected with the test port, and a common end of the test relay and the test port is connected with A/B/C-phase outgoing line interfaces through a phase change-over switch. The zero-power-outage test residual current operated intelligent protector realizes the purpose that client has no power outage when testing the residual current operated protector, improves the reliability of power supply, improves customer satisfaction, and prevents the occurrence of power-outage complaints and damages to the user interests caused by protector tests.
Description
Technical field
The utility model relates to a kind of electric power system detection field, particularly a kind of zero power failure test residual current acting intellective protector.
Background technology
Along with the raising of resident living level, also more and more higher to the requirement of power supply reliability.But traditional I and II RCD all can cause that client frequently has a power failure when test; not only can cause the household electrical appliance such as microcomputer, air-conditioning, refrigerator, TV, electric rice cooker to restart; affect the normal electricity consumption of client; part electrical equipment can be automatically out of service because frequently stopping power transmission; even can cause scrapping of production class enterprise product; power supply good service meeting reduces in the heart greatly client, and frequently has a power failure and reduced amount of power supply, has affected the economic benefit of enterprise.
Utility model content
According to above deficiency of the prior art, problem to be solved in the utility model is: provide a kind of power supply reliability high, effectively improve zero power failure test residual current acting intellective protector of the performance of enterprises.
The utility model solves the technical scheme that its technical problem adopts:
Zero described power failure test residual current acting intellective protector; comprise and be arranged in housing and connect successively zero-sequence transformer; control unit; actuating relay, release, release adapts with the disconnecting link that is connected inlet wire port; test reset switch is set between release and actuating relay; an actuating relay two ends busy relay in parallel, busy relay connecting test mouth, the common port of busy relay and test port is connected ABC three-phase outlet port by phase change-over switch.
Zero described power failure test residual current acting intellective protector is by applying I and II zero power failure test residual current acting intellective protector; make zero power failure test residual current acting intellective protector installation rate, operational percentage, test accuracy rate all reach 100%; when realization is tested RCD, client does not have a power failure; improve power supply reliability; improve customer satisfaction, prevent to complain event and the infringement to user benefit because of the power failure that protector test causes.
Preferred further, test reset switch is double-point double-throw switch.Power is large, and loss is little, and cost is low.
The beneficial effect that the utility model has is:
1) zero described power failure test residual current acting intellective protector can reduce the client's power failure causing because of company's reason, and client's loss is dropped to minimum.
2) the zero test residual current acting intellective protector that has a power failure described in is by 485 communication interfaces, and the real-time communication of realization and company's private server, can realize on-line testing.
3) the described zero test residual current acting intellective protector that has a power failure has retained when circuit or apparatus insulated reduction leakage current reach protector operating value, protector action, the performance of excision electric leakage circuit.The application of zero power failure measuring technology, has promoted RCD managerial skills, has greatly improved resident's power supply reliability.
Accompanying drawing explanation
Fig. 1 is the utility model structural principle block diagram.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As shown in Figure 1, described in the utility model zero has a power failure tests residual current acting intellective protector, comprise and be arranged in housing and connect successively zero-sequence transformer, control unit, actuating relay, release, release adapts with the disconnecting link that is connected inlet wire port, test reset switch is set between release and actuating relay, an actuating relay two ends busy relay in parallel, busy relay connecting test mouth, the common port of busy relay and test port is connected ABC three-phase outlet port by phase change-over switch, wherein, test reset switch is double-point double-throw switch.
Described in the utility model zero principle that has a power failure test residual current acting intellective protector is:
Described zero have a power failure test residual current acting intellective protector when operation protection circuit if any getting an electric shock or during electric leakage; protector will be through over-sampling; computer chip analyzing and processing drives tripping coil adhesive to disconnect major loop switch by actuator, to protect the safety of the person and equipment.In order to realize uninterrupted power test function, we install a double-point double-throw switch additional between actuator's actuating relay and release, disconnect closure while normally moving during test.And install a busy relay and actuator's interlock additional at protector output, by contact disconnection and the connecting test electric current of busy relay.The change over switch of throwing by a cutter three, to carrying out conversion testing between A, B, C three-phase, completes operating current, test operate time to protector, thereby has realized uninterrupted power test function.Tested and necessarily double-point double-throw switch has been got to closure state afterwards, protector has been switched to normal defencive function.
Claims (2)
1. residual current acting intellective protector is tested in zero power failure; comprise and be arranged in housing and connect successively zero-sequence transformer; control unit; actuating relay; release; release adapts with the disconnecting link that is connected inlet wire port; it is characterized in that: test reset switch is set between release and actuating relay; an actuating relay two ends busy relay in parallel; busy relay connecting test mouth, the common port of busy relay and test port is connected ABC three-phase outlet port by phase change-over switch.
2. zero power failure test residual current acting intellective protector according to claim 1, is characterized in that: described test reset switch is double-point double-throw switch.
