Novel auxiliary device for relay calibration

Technical Field

The utility model relates to a relay check-up field, in particular to novel auxiliary of relay check-up device.

background

A relay is an electric appliance that generates a predetermined step change in a controlled amount in an electric output circuit when a change in an input amount (excitation amount) meets a predetermined requirement. It has an interactive relationship between a control system (also called an input loop) and a controlled system (also called an output loop). It is commonly used in automated control circuits, which are actually a "recloser" that uses low current to control high current operation. Therefore, the circuit plays the roles of automatic regulation, safety protection, circuit conversion and the like. Relays generally have sensing mechanisms (input parts) that can reflect certain input variables (e.g., current, voltage, power, impedance, frequency, temperature, pressure, speed, light, etc.); an actuating mechanism (output part) which can realize the on and off control of the controlled circuit; between the input part and the output part of the relay, there is also an intermediate mechanism (driving part) for coupling and isolating the input quantity, processing the function and driving the output part.

Before the relay is put into use, a checking link is required, and the main checking item is to check the on-off of the relay contact. At present, the original verification method is: and adding a power supply to each relay, measuring the normally open contact and the normally closed contact of each relay, measuring the on-off of each pair of contacts one by one, and only checking one contact at each time. So, the check-up is inefficient, and the process is loaded down with trivial details, spends a large amount of manual works and time, can have the risk of electrocuting for relay power connection moreover at every turn.

The following detailed description of the present invention is provided in conjunction with the accompanying drawings, but it should be understood that the scope of the present invention is not limited by the following detailed description.

Throughout the specification and claims, unless explicitly stated otherwise, the word "comprise", or variations such as "comprises" or "comprising", will be understood to imply the inclusion of a stated element or component but not the exclusion of any other element or component.

As shown in fig. 1 and fig. 2, according to the utility model discloses novel auxiliary device of relay check-up of embodiment, it is used for verifying a plurality of relays simultaneously, can verify 14 foot relays (8 foot principle is the same), and every relay includes four pairs of normally open contact and four pairs of normally closed contact, and this auxiliary device includes action power, a plurality of relay bases, check-up power and pilot lamp. This embodiment explains the auxiliary device by checking 6 relays at the same time. The action power supply is used for providing action voltage for the relays, the number of the relay bases is consistent with that of the relays to be checked, the relay bases are connected into the action power supply in parallel, and the relay bases are used for installing the relays to be checked. With reference to fig. 1, fig. 1 shows an action circuit of a relay, wherein relays K1-K6 include four pairs of normally open contacts and four pairs of normally closed contacts, relay bases of 6 relays K1-K6 are connected in parallel and connected to a relay protection instrument, the relay protection instrument can be temporarily replaced by an adjustable direct-current 24V power supply and a voltmeter, and in addition, an open QF2 is connected into the action circuit.

As shown in fig. 2, fig. 2 shows a verification circuit for all normally open contacts and all normally closed contacts of the relay. All normally open contacts and all normally closed contacts of a plurality of relays are connected in series and then connected into a verification power supply, indicator lamps are connected into a series circuit of the normally open contacts and a series circuit of the normally closed contacts respectively, with reference to fig. 2, an indicator lamp H1 is connected into a series circuit of the normally open contacts of a relay K1, an indicator lamp H7 is connected into a series circuit of the normally closed contacts of a relay K1, an indicator lamp H2 is connected into a series circuit of the normally open contacts of a relay K2, an indicator lamp H8 is connected into a series circuit of the normally closed contacts of a relay K2, an indicator lamp H3 is connected into a series circuit of the normally open contacts of a relay K3, an indicator lamp H9 is connected into a series circuit of the normally closed contacts of a relay K3, an indicator lamp H4 is connected into a series circuit of the normally open contacts of a relay K4, an indicator lamp H10 is connected into a series circuit of the normally closed contacts of a relay K4, an indicator lamp H, insert pilot lamp H11 in the series circuit of the normally closed contact of relay K5, insert pilot lamp H6 in the series circuit of the normally open contact of relay K6, insert pilot lamp H12 in the series circuit of the normally closed contact of relay K6, the pilot lamp in the series circuit that the normally open contact belongs to, for example pilot lamp H1, or the pilot lamp in the series circuit of normally closed contact is not bright, for example pilot lamp H7, then all normally open contacts or all normally closed contacts in the series circuit that the pilot lamp that does not light belongs to judge for whole nonconforming.
