Embodiment Construction

[0024] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] The invention provides a portable relay calibration platform, such as figure 1 As shown, the entire platform is used in conjunction with the relay protection tester 3, including the selection switch 4 connected to the relay protection tester 3. After the selection switch 4, there are three test circuits, which are respectively DC 24V measurement circuit and AC 220V measurement circuit. Circuit, DC 220V measurement circuit, select the circuit through the selection switch 4. In the DC 24V measurement circuit, the DC 24V base 11 is connected to the selection switch 4 through the fuse 8; in the AC 220V measurement circuit, the AC 220V base 12 is connected to the selection switch 4 through the fuse 9; Switch 4 is connected.

[0026] The platform also includes a contact conversion measurement module 14 connected to each contact of the rela...

Abstract

The invention provides a portable relay calibration platform and a use method thereof. The system comprises a selection switch, three fuses and relay base areas, wherein the selection switch and the three fuses are sequentially connected with a relay protection tester, and the relay base areas are connected with the selection switch and the three fuses respectively. The system also comprises a platform power source module, resistance measurement modules and contact conversion measurement modules, wherein the resistance measurement modules are arranged at the two sides of a relay coil through bases, and the contact conversion measurement modules are connected to contacts of the relay coil through bases. According to the portable relay calibration platform and the use method thereof, contactindicator lamps serve as bases of judging joint conversion and judging whether or not the contacts are good, various types of special relay bases are used for meeting the calibration demands of relays different in voltage level and type, and a digital display resistance meter is used for directly measuring the direct resistance of the relays. The portable relay calibration platform and the use method thereof solve the problems that in the prior art, the calibration efficiency is low, all the contact and direct resistance measurement cannot be quickly calibrated, fault contacts cannot be quickly and accurately positioned, and the labor intensity of staff is high.

Description

technical field [0001] The invention belongs to the technical field of automatic devices of hydropower plants, and in particular relates to a portable relay calibration platform and a using method thereof. Background technique [0002] The relay is an electric control device, which is an electrical appliance that causes the controlled quantity to undergo a predetermined step change in the electrical output circuit when the change of the input quantity (excitation quantity) meets the specified requirements. Relays are widely used in the control loop of secondary equipment for safety protection, switching circuits, automatic adjustment, and power monitoring. A large number of relays are used in the secondary equipment of hydropower plants, and regular calibration is required to ensure that the status of the relays is normal. [0003] A relay calibration method commonly used at present: use the same type of relay base and relay protection tester for calibration. Relay verific...
