Embodiment Construction

[0014] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0015] The substation protection signal reset device of the present invention includes six modules: a network signal transceiver, a motor module, an automatic reset button device, a device signal summary module, a battery module, and a strong magnetic chuck; the specific structure is as follows:

[0016] Such as figure 2 As shown, the back of the housing 1 is provided with a strong magnetic chuck 16, an electromagnet is arranged inside the strong magnetic chuck 16, and a suction cup separation button 17 is installed outside the strong magnetic chuck 16 to control the power on and off of the electromagnet, and the housing 1 is powered on through the strong magnetic chuck 16. Afterwards, magnetic force is generated to adsorb on the front of the protection device; the front of the housing 1 is provided with an automatic reset button 5, and the a...

Abstract

The invention discloses an automatic returning device of a substation protection signal. The automatic returning device comprises a shell (1), wherein the back of the shell (1) is provided with a strong magnetic sucker (16), the strong magnetic sucker (16) is internally provided with an electric magnet, a sucker separation button (17) is installed outside the strong magnetic sucker (16) so as to control the electric magnet to be on or off, the shell (1) is adsorbed on the front of a protection device through the strong magnetic sucker (16), the front of the shell (1) is provided with an automatic returning button (5), and the automatic returning button (5) is driven by a motor in the shell (1) through a transmission mechanism so as to press a returning button on the front of the protectiondevice. The automatic returning device makes operation and maintenance more efficient and quick, realizes network-based management of an unattended substation, saves a lot of time, manpower and materials, optimizes construction of an operation and maintenance group thoroughly, and guarantees devices to run safely and stably in the first time.

Description

technical field [0001] The invention belongs to the field of electric equipment, in particular to an automatic signal reset device on a substation protection device, that is, a device for automatically pressing a reset button on the protection device. Background technique [0002] In order to reset the abnormal signal of the protection device at the first time, it is necessary for the operation and maintenance personnel to drive to the site for manual reset at the first time, so as to ensure the safe and stable operation of the protection secondary equipment. But now most substations of 500kV and below in our province are managed by unattended operation and maintenance teams. The operation and maintenance personnel need to go to the site to perform manual reset. Due to the different voltage levels, the number of stations under the jurisdiction of each operation and maintenance team is also different. Under the influence of road conditions, weather and other factors, the time...
