Embodiment Construction

[0023] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0024] Such as figure 1 A control system based on a grounding resistance cabinet is shown, including a current monitoring module, a voltage monitoring module, a central processing unit, a remote transceiver module, a remote transceiver module, a network server, a data server, a data storage unit, and a data dispatch center;

[0025] Among them, the current monitoring module is used to collect the real-time current signal of the neutral point grounding resistance and send it to the current transformer;

[0026] The voltage monitoring module is used to collect the real-time voltage signal of the neutral point grounding resistance and send it to the voltage transformer;

[0027] The current transformer converts the collected current signal into a low current signal and sends it to the signal conditioning module, and the voltage transfo...

Abstract

The invention discloses a control system based on a grounding resistance cabinet. The control system comprises a current monitoring module, a voltage monitoring module, a central processor, a remote transmitting and receiving module, a remote transmitting and receiving module, a network server, a data server, a data storage unit, a data dispatching center and a keyboard module, wherein the keyboard module is used for acquiring an instruction input by manual, the network server is used for being data interaction connection with Internet, and the data server is used for storing various current/voltage parameters. By the control system, comprehensive detection and statistics of the grounding resistance state of the whole power system are achieved, more real-time and convenient monitoring of a power state is performed by a user, local management and remote management can be achieved, the problem is timely and effectively found out and solved, intelligent control of the power system is achieved by matching with the data dispatching center, and the production efficiency and the benefit are improved.

Description

technical field [0001] The invention belongs to the field of power systems, in particular to a control system based on a grounding resistance cabinet. Background technique [0002] The neutral point grounding resistance cabinet is a supporting device for grounding resistance in the 220V ~ 1000V low voltage system. In order to improve the quality of power supply of 1000V / 660V / 380V / 220V low-voltage plant power system and reduce the power failure of the motor circuit caused by frequent single-phase ground faults, the low-voltage power system in the main building of the power plant should be grounded with high resistance. This not only prevents the circuit breaker from tripping immediately when the single-phase is grounded, but also reduces the probability of the motor being burnt out when the motor is in two-phase operation when the fuse is used as a protective device. [0003] The parameter data of the traditional grounding resistance cannot be effectively obtained in real ti...
