Embodiment 1

[0040] Such as figure 1 As shown, the present invention provides a box-type substation with relay protection function. The present invention divides the space of the box-type transformer station into a relay maintenance room, and independently installs the relay in the relay maintenance room, so it is convenient Frequent and multiple maintenance of relays avoids searching for maintenance relays in the entire transformer assembly, and improves the simplicity and convenience of relay maintenance work.

[0041] It specifically includes a box body 1 and a box door 2 arranged on the front of the box body 1. A low-pressure chamber 3, a voltage transformation chamber 10 and a high-pressure chamber 11 are sequentially arranged in the box body 1. The low-voltage components are connected to the voltage-transforming components in the voltage-transforming chamber 10 through relays 9 , and the voltage-transforming components in the voltage-transforming chamber 10 are connected to the high-...

Embodiment 2

[0063] Such as Figure 5 As shown, the box-type transformer substation of the present invention will be described in detail below to realize the relay 9 for transformer safety control. An electrical appliance with a step change. It has an interactive relationship between the control system (also known as the input loop) and the controlled system (also known as the output loop). Usually used in automatic control circuits, it is actually an "automatic switch" that uses a small current to control the operation of a large current. Therefore, it plays the role of automatic adjustment, safety protection, and conversion circuit in the circuit.

[0064] The relay 9 includes a protective shell 901 and a hollow bottom plate 902 arranged inside the protective shell 901. An insulating control bridge 903 is hinged on the hollow bottom plate 901. The upper surface of the hollow bottom plate 902 is close to the insulating control bridge 903. A compression spring 904 is provided at the hin...

Abstract

The invention discloses a box-type substation with a relay protection function. The box-type substation comprises a box body and a box door arranged on the front face of the box body. The box body isprovided with a low-voltage chamber, a voltage transformation chamber and a high-voltage chamber in sequence; a low-voltage assembly in the low-voltage chamber is connected with a voltage transformation assembly in the voltage transformation chamber through a relay; the voltage transformation assembly in the voltage transformation chamber is connected with a high-voltage assembly in the high-voltage chamber; the relay is arranged in a relay maintenance chamber between the low-voltage chamber and the voltage transformation chamber; open sliding grooves are transversely formed in the two side walls, right facing the low-voltage chamber and the voltage transformation chamber, of the relay maintenance chamber; a maintenance door communicated with the relay maintenance chamber is formed on theback face of the box body; and the relay slides along the open sliding grooves. According to the scheme, the relay is independently installed in the relay maintenance chamber, so that the relay can befrequently maintained for multiple times conveniently, the relay is prevented from being searched and maintained in the whole transformer assembly, and the relay maintenance work is simple and convenient.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of transformer substations, in particular to a box-type transformer substation with a relay protection function. Background technique [0002] A substation is a place in a power system that transforms voltage and current, receives electric energy and distributes electric energy. The substation in the power plant is a step-up substation, whose function is to boost the electric energy generated by the generator and feed it to the high-voltage grid. [0003] Box-type transformer substation is a typical representative of substation. It is a kind of high-voltage switchgear, distribution transformer and low-voltage power distribution device. It is a factory prefabricated indoor and outdoor compact power distribution equipment arranged according to a certain wiring scheme. High voltage, low voltage power distribution and other functions are organically combined, installed in a moisture-proof,...
