Abstract
The invention discloses a system for intelligently regulating a grounding resistance of transformer substation grounding net. The transformer substation grounding net comprises a horizontally paved grid and a vertical grounding electrode connected with the grid. A measuring module of the grounding resistance of the grounding net is connected to the transformer substation grounding net in order to measure the resistance value of the transformer substation grounding net; a real-time monitoring module of the grounding resistance is connected with the measuring module of the grounding resistance of the grounding net so as to collect, calculate, statistically analyze, compare, remote control and store the measured value of the measuring module of the grounding resistance of the grounding net; and a resistance-decreasing material supplement module is connected with the transformer substation grounding net and is controlled by the real-time monitoring module of the grounding resistance in order to supplement the resistance-decreasing material to the transformer substation grounding net and keep the grounding resistance of the transformer substation stable.
Description
Technical field
The present invention relates to a kind of system for intelligently regulating grounding resistance of transformer substation grounding net, belong to the lightning protection grounding network technical field.
Background technology
Grounding net of transformer substation through the calculating at initial stage with lay after generally be can not calculate its follow-up resistance value again, but in the use of reality, substation grounding resistance can change at any time, the principal element that influences grounded screen electric resistance is landform, geological conditions, next is meteorological conditions such as climate condition and fine, rain, also has factors such as the ground network area in addition.The cause in use grounding resistance of ground network changes at any time; and As time goes on and gradually its variation so that can reduce (loss of resistance-lowering material); when the resistance value of grounding net of transformer substation exceeds fixed range with easily generation accident, crisis country and individual's safety.
Summary of the invention
The technical problem to be solved in the present invention is, provides a kind of Resistance of Grounding Grids of monitoring substation at any time to change, and the system for intelligently regulating grounding resistance of transformer substation grounding net that intelligence is adjusted its resistance can overcome the deficiencies in the prior art.
Technical scheme of the present invention: it comprises system for intelligently regulating grounding resistance of transformer substation grounding net
Grounding net of transformer substation, grounding net of transformer substation is made of level grid of laying and the vertical junction ground electrode that is connected on the grid;
The ground network ground resistance measurement module, it is online to be connected substation grounding, is used for the measurement to the grounding net of transformer substation resistance value;
The real-time monitoring modular of earth mat resistance is connected with the ground network ground resistance measurement module, is used for that measured value with the ground network ground resistance measurement module gathers, calculating, statistics, comparison, remote operation control and preserve;
The resistance-lowering material complementary module, it is connected with grounding net of transformer substation, controlled by the real-time monitoring modular of earth mat resistance, is used for replenishing resistance-lowering material to grounding net of transformer substation, makes substation grounding resistance keep stable.
Grounding net of transformer substation is spliced mutually to form by the metal pipe material that is interconnected and constitutes.
Grounding net of transformer substation is that the plastic tube that binding is interconnected on existing grid and vertical electrode constitutes.
The ground network ground resistance measurement module is by humidity, acid-base value, the density index measurement of soil being finished the calculating of resistance value.
Compared with the prior art, the present invention is by connecting the ground network ground resistance measurement module on the net in existing substation grounding, on the ground network ground resistance measurement module, connect the real-time monitoring modular of earth mat resistance, so in use can measure monitoring to the online resistance value of substation grounding at any time, the real-time monitoring modular of earth mat resistance sends working signal to the resistance-lowering material complementary module when grounding net of transformer substation resistance overshoot scope, replenish resistance-lowering material to vertical junction ground electrode place, make substation grounding resistance keep stable, the resistance value of guaranteeing grounding net of transformer substation resistance can the overshoot scope, has guaranteed the safety of transformer station.Grounding net of transformer substation can be spliced mutually to form and constitutes by the metal pipe material that is interconnected, convenient like this to the additional resistance-lowering material of each vertical junction ground electrode, can finish by the plastic tube that binding on grid and vertical electrode is interconnected the transformation of existing earthing electric network.The setting of the real-time monitoring modular of earth mat resistance simultaneously also can bring more fully data to the follow-up developments of substation grounding resistance.
